Feyenoord's expected tilt at the Dutch Eredivisie title got off to a false start after they went down 2-1 at PEC Zwolle in their opening match of the season this afternoon.
The visitors from Rotterdam are among the favourites to challenge for top honours this term after finishing third last season, but looked out of sorts on Sunday and fell behind to Mateusz Klich's opener in the 65th minute.
Feyenoord looked to have salvaged a point when Ruben Schaken levelled three minutes from the end, but Zwolle had other ideas and claimed all the points when substitute Guyon Fernandez slotted home in stoppage time.
Last year's surprise package Vitesse Arnhem kicked off with a 3-1 win at home to Heracles Almelo.
Vitesse mounted an unlikely challenge last season that only foundered over the final fixtures, but endured a bruising summer with star men Wilfried Bony and Marco van Ginkel leaving for the Barclays Premier League.
However, they shrugged off their losses with an assured display today, goals from Kelvin Leerdam (27), Marcus Pedersen (31) and Renato Ibarra (82) sealing a one-sided win before Matthew Amoah pulled one back for Heracles late on.
FC Utrecht and newly-promoted Go Ahead Eagles drew 1-1. Utrecht went ahead through Dave Bulthuis after 15 minutes, but the top-flight new boys levelled through Xander Houtkoop a minute after the restart.
Cambuur Leeuwarden, promoted as Eerste Divisie champions at the end of last season, began their campaign with a goalless draw at home to NAC Breda.
Russian Premier League
Spartak Moscow's 100 per cent start to the Premier League season was ended by a 2-2 draw away to Kuban Krasnodar on Sunday.
Emmanuel Emenike gave Spartak a first-half lead but substitute Balde Ibra equalised midway through the second period and Angel Dealbert put the hosts, fresh from a 2-0 win over Scottish side Motherwell in the first leg of their Europa League third qualifying round clash, ahead.
Yura Movsisyan scored four minutes after coming off the bench to ensure the league leaders remain unbeaten but they still dropped points for the first time.
Third-placed CSKA Moscow were held to a 0-0 draw away to Rubin Kazan and the day's other game, between Amkar Perm and Krylya Sovetov, also finished goalless.
Swiss Super League
Young Boys made it four wins from four at the start of the new Super League season with a 3-1 victory at FC Zurich.
First-half goals from Alexander Gerndt and Michael Frey put Young Boys in charge and, after Zurich had pulled a goal back through Alain Nef just before the hour mark, the visitors wrapped up the scoring and the win with a 90th-minute third from replacement Yuya Kubo.
Pacesetters Young Boys, the only side still boasting a 100 per cent record, are now three points clear of second-placed Lucerne, who beat Sion 1-0 on Sunday with an 83rd-minute winner from Oliver Bozanic.
In Sunday's other game, Aarau salvaged a point from their trip to Thun thanks to a 90th-minute equaliser from Davide Calla.
Calla had given Aarau the lead with a fourth-minute penalty but goals from Benjamin Luthi (10) and Berat Sadik (27) turned the game Thun's way before Calla's late heroics saw the spoils shared.
Malmo ended a disappointing week on a positive note on Sunday with a 3-1 away win over Halmstad that lifts them to within two points of Allsvenskan leaders Helsingborg.
Malmo came into the game having surprisingly lost 2-0 at lowly Gefle last weekend before slumping to a 4-0 Europa League loss at the hands of Swansea on Thursday, but they got back to winning ways today.
Early goals from Magnus Eriksson (12) and Jiloan Hamad (21, penalty) put Malmo in charge and they added a third in the 64th minute through Tokelo Rantie.
Halmstad got on the scoresheet through Richard Magyar's goal just before half-time when 2-0 down but they could not get any closer and ended up finishing with 10 men after Kristinn Steindorsson was sent off late on.
Fourth-placed IFK Gothenburg were also celebrating a 3-1 win, although they needed to come from behind to defeat out-of-form Hacken.
A third-minute strike from Moestafa El Kabir put Hacken in front but goals from Tobias Hysen (38), Robin Soder (39) and Jakob Johansson (69) turned the game around as IFK inflicted a fourth successive league defeat on their opponents.
In Sunday's other match, an 86th-minute penalty from Daniel Sjolund earned Atvidaberg a 1-1 draw at home to Gefle, who had taken a 53rd-minute lead through Mikael Dahlberg.
Belgian Jupiler League
Geoffrey Mujangi Bia continued his impressive recent form with all three goals as Standard Liege defeated Lierse 3-0 to make it two wins from two at the start of the new Jupiler Pro League season.
The Belgium international, who also scored in last weekend's season-opening 2-0 win at Mechelen and in Thursday's Europa League triumph over Xanthi, opened his account for the match in the 17th minute before adding a second three minutes later.
The 23-year-old then completed his hat-trick in the 66th minute to leave Standard as one of five teams boasting 100 per cent records after two rounds.
Club Brugge also have six points after beating KV Oostende 2-1 away from home today, goals from Bjorn Engels (three) and Boli Bolingoli Mbombo (64) sandwiching an equaliser from Frederic Brillant (23).
Gent were also celebrating 2-1 win, although they needed to come back from a goal down to defeat Mechelen.
The visitors took a 24th-minute lead through Benjamin Mokulu but goals from Ilombe M'Boyo (55) and Carlos Diogo (88) turned the match in Gent's favour before Mechelen lost David Destorme to a late red card.
FC Copenhagen's miserable start to the new Superliga season continuedon Sunday as the defending champions slumped to a 3-1 home defeat to Randers.
FCK had lost both of their opening two games but were briefly on course for victory today in their first home fixture after taking a 24th-minute lead through Thomas Delaney.
However, that advantage lasted just 11 minutes before Ronnie Schwartz drew Randers level and then two late goals saw the visitors claim all three points, Jonas Borring netting in the 75th minute and Nicolai Brock-Madsen adding a third four minutes later.
The result leaves FCK bottom of the standings and nine point adrift of pacesetters Midtjylland.
In second place are Esbjerg on six points following their 2-0 win at Brondby today, a second-half brace from substitute Jesper Rasmussen (68 and 72 minutes) earning last season's Danish Cup winners the spoils.
Sunday's other match saw Odense pick up their first victory with a 4-2 home triumph over Viborg. Bashkim Kadrii (29 and 30), Emil Larsen (58) and Rasmus Falk Jensen (71) netted for Odense with Mikkel Rask (44) and Thomas Dalgaard (87) replying for the visitors.
