The transfer window closes at 11pm BST on Wednesday so we take a look at what the Premier League’s big boys still need to do.
With the expected arrival of Shkodran Mustafi from Valencia and Lucas Perez from Deportivo, the Gunners have fulfilled their two main needs in grabbing a new central defender and a pacey striker.
Arsenal, however, are a team that continually suffers injury problems so it is possible that Arsene Wenger will look to bring in another defensive player for squad security.
Despite being a World Cup winner, Per Mertesacker has often struggled with the pace of the Premier League, while Gabriel Paulista has not yet fully convinced and Calum Chambers is set to leave.
New boy Rob Holding looks to have plenty of potential but perhaps a more experienced defender, one that can play across the back four, would still be beneficial as the Gunners look to mount a more serious title challenge this season.
Having made a strong start to the season under new boss Antonio Conte, you could argue that Chelsea don’t really need to do too much more business but defensively they definitely do.
Conte has shown at Juventus, and with Italy, that he sometimes prefers to switch to a back three but he doesn’t really have the tools at his disposal to do that at the moment.
Kalidou Koulibaly, Ricardo Rodriguez, Giorgio Chiellini and Alessio Romagnoli have all been linked with the Blues in recent weeks so it’s clear that Conte wants a new central defender, particularly one that he feels can be a long-term successor to Stamford Bridge stalwart John Terry.
Let’s think long and hard about this one, or maybe not! A new left-back must be on the cards for Jurgen Klopp after Alberto Moreno’s struggles in the last 18 months.
James Milner has been doing a steady job – as he always does – in the position, but a more natural left-sided option is definitely needed. Leicester’s Christian Fuchs is the latest player to be linked with a move to Anfield.
With the way the Reds have raided Southampton in the last couple of years it’s also a surprise that they haven’t put a bid in for Ryan Bertrand, but perhaps Klopp is of the opinion that Milner can grow in the position and that a panic buy is not necessary at this stage.
Pep Guardiola has said that City’s transfer business is done for this window but they have money to burn and are a club that are always on the lookout for players to improve them.
Sergio Aguero is the best striker in the Premier League but Sergio Aguero is also injury-prone, so could City look to boost their central striking options as the clock counts down?
Wilfried Bony looks set to be on his way out of the club so that will free up a spot on the squad. In other words, watch this space!
Jose Mourinho did the majority of his business early on but it’s no real secret that in recent weeks United have been looking to bring in another defender.
Eric Bailly and Daley Blind have so far looked a good pairing at the heart of United’s defence and Chris Smalling is still in the mix. Mourinho, however, does not seem to be a big fan of Phil Jones, while you also wonder how long it will take other teams to work out that Antonio Valencia is not a natural right-back – he’s gotten away with it so far.
Monaco full-back Fabinho and Southampton star Jose Fonte have been linked with Old Trafford moves but it remains to be seen if Jose wants to dip into the market again.
When everyone is fit there is no doubt that Spurs have one of the most balanced squads in the Premier League but with several players leaving this summer, Mauricio Pochettino still wants to bring in one or two more.
Attacking wide players is the main area that Pochettino has highlighted, with Crystal Palace winger Wilfried Zaha still a major target, while Marseille’s Georges-Kevin N’Koudou is finally expected to complete his swap deal with Clinton N’Jie going the other way.
The game against Liverpool at the weekend highlighted the need for more pace in the wider and central striking positions, given that Liverpool’s high pressing game gave the defenders no real out-ball.
Newcastle forward Ayoze Perez has long been rumoured to be a major Spurs target and he would certainly fit that bill if Pochettino does indeed desire another striking option.
Note: It would be rude not to mention the champions, Leicester City, and Claudio Ranieri has certainly not rested on his laurels after bringing in six players already.
The Foxes have reportedly had a £25million bid for Sporting Lisbon striker Islam Slimani rejected, so it’s clear that Claudio still feels a need to strengthen despite their remarkable title triumph last season.
