PSV Eindhoven stunned Ajax with a second-half goal blitz as they routed the defending champions 4-0 to climb to the top of the Eredivisie standings.
After a goalless opening period, PSV ran riot during a 15-minute spell after the break when they scored four times without reply to end a run of six competitive matches without a win in emphatic fashion.
Tim Matavz opened the floodgates in the 53rd minute following a mistake by Ajax keeper Kenneth Vermeer and then Jetro Willems (61), Oscar Hiljemark (64) and Park Ji-sung (68) struck in rapid succession to finish off the visitors, who also lost by four goals to nil to Barcelona in the Champions League on Wednesday.
The result sees PSV, who suffered a shock 2-0 home loss to Ludogorets in the Europa League on Thursday, move two points clear of the top of the standings after previous pacesetters PEC Zwolle slumped to a second successive defeat, going down 3-0 at Vitesse Arnhem.
On-loan Chelsea forward Lucas Piazon scored twice for Vitesse, with his goals in the 35th and 88th minutes sandwiching a strike from Kelvin Leerdam (68).
Feyenoord continued their improved form with a 1-0 home win over FC Utrecht, Tonny Vilhena netting the only goal 10 minutes before half-time, while in Sunday's other Eredivisie match NAC Breda beat AZ Alkmaar 3-0.
Danny Verbeek, Rydell Poepon and Elson Hooi all struck second-half goals for NAC who have now won back-to-back matches and scored eight times in the process having started the season with three defeats and two draws.
Swiss Super League
Basel capped a wonderful week with a 3-1 victory at FC Sion which moved them into a share of top spot in the Swiss Super League.
Murat Yakin's men enjoyed a stunning 2-1 success at Chelsea in the Champions League in midweek and carried that momentum into Sunday's game at the Stade Tourbillon.
Having fallen behind to Leo Itaperuna's 23rd-minute opener Basel equalised through Valentin Stocker eight minutes later.
The visitors' position was strengthened five minutes into the second half when Sion's Xavier Kouassi was dismissed and the 10 men struggled thereafter, Basel going on to win with goals from Giovanni Sio and Marco Streller.
The win takes Basel on to 15 points, the same as Young Boys who suffered their third successive Super League defeat on Saturday at home to Lucerne.
Grasshoppers moved back up to third with a 2-1 defeat of FC Thun.
Izet Hajrovic's penalty and a Milan Vilotic goal put Grasshoppers in charge with Thun's sole consolation coming via substitute Berat Sadik seven minutes from time.
Lausanne remain rooted to the foot without a win following a 2-1 defeat at home to FC Zurich.
The hosts' Sebastien Meoli cancelled out Jorge Teixeira's opener but any hope Lausanne had evaporated with the 80th-minute sending off of Yaya Banana.
Zurich capitalised on the man advantage and secured the win when Philippe Koch scored in the final minute.
Russian Premier League
Spartak Moscow moved above city rivals CSKA into second place in the Premier League with a 3-0 win in Sunday's local derby, while Zenit St Petersburg moved to the summit.
Goals from Spartak's Aras Ozbiliz, Dmitri Kombarov and Sergei Parshivlyuk sunk previous leaders CSKA and victory for Zenit left all three teams level on 20 points after nine games of the season.
Rostov held Zenit at bay until half-time but Danny's 51st-minute goal opened the floodgates, with Andrey Arshavin, Hulk and Viktor Faitzulin giving the visitors a comfortable 4-0 success.
Anzhi Makhachkala remained winless and second from bottom after a 2-1 defeat at Volga Nizhny Novgorod.
Shota Bibilov gave the hosts an 11th-minute lead and there followed a bizarre spell, with Anton Putsila doubling his side's lead but then putting through his own goal just 60 seconds later.
Amkar Perm scored three times in the first 16 minutes to beat Kuban Krasnodar 3-0, the goals coming from Blagoy Georgiev, Martin Jakubko and Georgi Peev.
Tomsk came from behind to beat 10-man Rubin Kazan 2-1.
Jose Salomon Rondon gave Rubin a 15th-minute lead but the dismissal of Alexander Ryazantsev turned the game. Kirill Panchenko netted the resulting penalty and Maksim Bordachev scored Tomsk's winner.
Malmo opened up a three-point lead at the top of the Allsvenska standings by beating IFK Norrkoping 2-0 away from home while nearest challengers Helsingborg were held at home by bottom side Syrianska.
Malmo's bid to reclaim the title they last won in 2010 suffered a blow last time out when they were beaten 2-0 at home by Djurgarden, but they responded in winning fashion on Sunday thanks to goals in either half from Guillermo Molins and Jiloan Hamad.
And there was further good news for the leaders as second-placed Helsingborg dropped points in a 2-2 draw with 10-man Syrianska.
Dinko Felic put the lowly visitors ahead in the 10th minute but Helsingborg hit back to take the lead through a brace from Imad Khalili, who netted in the 38th and 62nd minutes.
Helsingborg were only ahead for two minutes before Sebastian Rajalakso drew Syrianska level, but the hosts received a boost almost immediately when the away side lost Haris Skenderovic to a red card.
That left Helsingborg with 25 minutes to try and find a winner against 10 men but they could not manage it and will head into Wednesday's top-of-the-table showdown with Malmo trailing the pacesetters by three points.
Also on Sunday, Djurgarden continued their good run of form with a 2-0 win over Atvidabergs, Erton Fejzullahu (26) and Peter Nymann (54) on the scoresheet, while second-bottom beat Hacken 1-0 thanks to a 79th-minute winner from Panajotis Dimitriadis.
Hacken had to play the whole second half a man down following Simon Gustafsson's red card.
There were also two red cards in the match between Mjallby and Elfsborg, which finished in a 2-2 draw.
Par Eriksson put Mjallby ahead in the fourth minute but fifth-placed Elfsborg drew level 20 minutes later from a Lasse Nilsson penalty after the home side had Gbenga Arokoyo sent off.
Elfsborg then took a 38th-minute lead through Sebastian Holmen but they could not hold on for victory as Eriksson's second on the hour made it 2-2. Elfsborg then lost their numerical advantage as well, with Nilsson being handed his marching orders 16 minutes from time.
Greek Super League
Greek Super League leaders Olympiacos surrendered their 100 per cent record in Sunday's goalless draw at Panetolikos.
The reigning champions had won their four opening games but could not find a way through against the newly-promoted team from Agrinio, who have made a steady start by taking five points from five games.
A disappointing evening for Olympiacos left the door open for PAOK Salonika, who narrowed the gap on the leaders to a single point as substitute Zvonimir Vukic scored the only goal of a 1-0 win over Platanias.
Panthrakikos beat 10-man Veria by the same scoreline to reach sixth in the embryonic table, Igor De Souza notching the winner before Konstantinos Barbas saw red late on.
Giannina's progress up the table hit a wall at Levadiakos, who won 1-0 through a Giorgos Lambropoulos goal, while the points were shared from a 1-1 draw between Ergotelis and Panionios.
Marcos Bambam set Ergotelis on course for their second win of the season but Christos Aravidis rescued a draw with a penalty on the stroke of full-time.
FC Copenhagen and Brondby continued to improve in the Danish Superliga but FC Nordsjaelland look likely to remain bottom for a little while longer.
Reigning champions Copenhagen had found themselves at the wrong end of the table with just one win from seven opening games but reached the 10-point barrier with a 2-1 win over Odense in the capital.
They had to come from behind to clinch it, though, after Odense's Emil Larsen opened the scoring midway through the first half. Thomas Delaney (74) and Igor Vetokele (83) scored after the break to turn the game on its head.
Ten-time Danish champions Brondby picked up their first win of the season last week and a 3-1 victory at Aarhus on Sunday saw them move to within a point of safety.
Simon Makienok scored a goal in either half before Casper Sloth hit back for Aarhus, but substitute Kenneth Zohore made the points safe with his 69th-minute strike.
There was a sixth defeat of the season for basement boys Nordsjaelland, who lost 2-0 at Sonderjyske thanks to goals from Bjorn Paulsen and Johan Absalonsen and are four points adrift.
French Ligue 1
The battle of the big spenders ended all square as Paris St Germain and Monaco had to settle for a 1-1 draw at the Parc des Princes on Sunday night which kept the visitors top of Ligue 1.
Zlatan Ibrahimovic converted a Maxwell cross to put the capital club into an early lead, but Radamel Falcao bravely headed home an equaliser within 15 minutes to ensure Monaco maintained their unbeaten start to the season.
The hosts had the better chances, but the wasteful Ibrahimovic was guilty of over-playing at times, missing three golden chances.
The draw kept Monaco two points clear of PSG and St Etienne.
Nice took no time at all to settle into their new home, producing a convincing 4-0 win over struggling Valenciennes at the brand new Allianz Riviera.
Claude Puel's men stretched their unbeaten run to five games in Ligue 1 thanks to first-half goals from Dario Cvitanich and Eric Bautheac, which were followed up by strikes from Christian Bruls and Alexy Bosetti to lift Nice into fifth place.
Defeat for goal-shy Valenciennes means they have now suffered five consecutive losses since their opening day win over Toulouse and they continue to languish in the bottom three.
Lyon had to come from behind to beat Nantes 3-1 at the Stade de Gerland and register a first Ligue 1 win in four attempts.
Despite falling behind to a Jordan Veretout goal, Les Gones hit back with goals from Bafetimbi Gomis, Clement Grenier and Jimmy Briand and closed to within four points of Monaco.
Defeat for Nantes leaves them without a win on the road in three attempts but Les Canaris' solid home record means they sit happily in mid-table on their return to the top flight.
Lorient twice fought back from behind to take a share of the spoils from a 3-3 Ligue 1 draw with out-of-form Bordeaux.
The visitors had lost three games in a row going into the match but took an early lead at Stade du Moustoir through a Cheick Diabate penalty.
Lorient levelled through Vincent Aboubakar but found themselves 3-1 down before the half-hour mark as Gregory Sertic and Henri Saivet put Francis Gillot's in control of the game.
Kevin Monnet-Paquet pulled a goal back on the stroke of half-time and the hosts grabbed an equaliser when Sadio Diallo struck on 58 minutes to earn a point.
Portuguese Primeira Liga
Porto dropped their first points of the season as they were held to a 2-2 draw at Estoril on Sunday.
Lica put the Liga leaders in front after 26 minutes, but Evandro levelled with a 35th-minute penalty.
Jackson restored Porto's lead in the 66th minute, but again they could not hold on to it as Luis Leal made it 2-2 nine minutes from time.
The draw moved Porto one point clear of Braga at the top of the table.
Benfica closed the gap on Porto to three points with a 1-0 win at 10-man Guimaraes.
The hosts had David Addy sent off in the 61st minute and Oscar Cardozo ensured Benfica took advantage with the winner in the 73rd minute.
Mario Rondon's 33rd-minute goal earned Nacional a 1-0 home success over Academica.
Belgium Pro League
Standard Liege made it eight wins from eight in the Pro League with a 2-1 home win over Lokeren on Sunday.
The leaders went in front through Imoh Ezekiel's opener after 18 minutes, but Hans Vanaken levelled in the 38th minute.
Michy Batshuayi got the winner on the stroke of half-time to ensure Standard maintained their perfect start to the campaign.
The win kept the home side four points clear of Club Brugge, who thumped Anderlecht 4-0.
Timmy Simons broke the deadlock in the 31st minute with a penalty and Maxime Lestienne (59, 75) scored twice to take the game away from the visitors.
Kehinde Fatai completed the rout.
Zulte-Waregem moved up to third as they scored four second-half goals to win 4-2 at home to OH Leuven.
Mohamed Messoudi put Leuven 1-0 up at the break and Evariste Ngolok put them 2-1 ahead just after the hour mark, minutes after Habib Habibou and equalised.
But Habibou levelled again in the 72nd minute before two goals in the last five minutes from Idrissa Sylla and Sven Kums sealed the comeback.
The match between Waasland-Beveren and Genk was goalless.
