Ranking every Premier League club's summer transfer window from best to worst

With the Premier League season just a day away from kick-off, clubs are continuing to put the finishing touches on their squads in preparation for the big push.

The window remains open until the end of August, but most clubs have been attempting to finalise their squads prior to the opening weekend of action.

Some clubs have been more successful than others in achieving this, while Wolves even lost their manager on Tuesday when Julen Lopetegui left by mutual consent.

His replacement, Gary O'Neil, will take charge of a squad that has lost plenty of star talent, including captain Ruben Neves - an example, thus far, of how a transfer window can potentially shape a season.

At the other end of the spectrum, Arsenal and Newcastle have both had strong windows, while Manchester City have continued to build on their treble-winning squad.

With all that in mind, let's take a look at each club's performance so far in the window (via Tiermaker).

Perfect - Arsenal, Brighton

Arsenal boss Mikel Arteta was adamant that his squad needed more depth - and Gunners chiefs have delivered with deals for Declan Rice, Jurrien Timber and Kai Havertz. David Raya is also closing in on a transfer from Brentford.

Fringe players have also been transferred away from the Emirates Stadium, although Arteta will need to replace the leadership void left by Granit Xhaka's departure.

Brighton, meanwhile, have also recruited well with the signings of Mahmoud Dahoud, Joao Pedro and James Milner. Roberto De Zerbi also has a new goalkeeper in Bart Verbruggen.

The remainder of their window, meanwhile, will depend on whether they can keep hold of Moises Caicedo.

Very good - Manchester City, Aston Villa, Luton, Tottenham, Newcastle, Manchester United

City's double acquisition of Croatian duo Josko Gvardiol and Mateo Kovacic puts them in a strong position to build on last year's treble success.

Aston Villa, meanwhile, have completed moves for highly-rated pair Pau Torres and Moussa Diaby, and the perhaps underrated signing of Youri Tielemans from Leicester, as they prepare for a European campaign.

Luton have been financially sensible ahead of their first Premier League season, and have largely recruited talent from the EFL. Ross Barkley, signed on a free transfer, could be a shrewd addition.

Tottenham and Newcastle have both brought in talent both in attack, midfield and defence - Sandro Tonali's arrival on Tyneside could be one of the signings of the season. The overall success of Spurs' window will depend on whether Harry Kane stays.

Then there is Manchester United, who have improved their squad with the signings of Andre Onana, Mason Mount and Rasmus Hojlund. Erik ten Hag's next big job is to sell squad players.

Decent - Fulham, Bournemouth, Brentford, Burnley, Nottingham Forest

Fulham's transfer window hasn't exactly been smooth sailing, with star striker Aleksandar Mitrovic and manager Marco Silva both linked with moves to Saudi Arabia. Neither move has materialised, but the future of Mitrovic is uncertain. Raul Jimenez is a solid pickup from Wolves, as is defender Calvin Bassey from Ajax.

Bournemouth's business under Andoni Iraola thus far has been solid. Justin Kluivert will excite Cherries fans, but they have also lost talented full-back Jordan Zemura and defensive midfielder Jefferson Lerma.

Brentford secured a permanent deal for striker Kevin Schade after a successful loan spell, and defender Nathan Collins has arrived from Wolves. There may still be an Ivan Toney-shaped gap in the squad, though - for now.

Burnley have recruited well as Vincent Kompany looks to establish the Clarets as a Premier League club once again. England U21 international James Trafford has arrived from City, while defender Jordan Beyer has turned his loan spell from Monchengladbach into a permanent deal. They do look light up front for now, though.

Nottingham Forest haven't signed 30 players like last season, but have secured a trio of new signings, including Anthony Elanga from Manchester United. Matt Turner, arrived from Arsenal, will be Steve Cooper's number one goalkeeper.

Room for improvement - Chelsea, Liverpool, Everton, Crystal Palace

It has been a mixed window for Chelsea, which has seen them bring in Christopher Nkunku as their marquee signing. Nicolas Jackson has great potential, while Axel Disasi is a solid signing in defence, but the squad is (somehow, after last season's spending) looking light, particularly in midfield.

Liverpool's 'summer rebuild' has seen them bring in Alexis Mac Allister and Dominik Szoboszlai - but Jurgen Klopp wasn't planning on Fabinho and Jordan Henderson joining the club's midfield exodus. Efforts to sign Romeo Lavia have stalled, and the defence could do with improvement too.

Everton's financial concerns are well-known, but only two players have been signed at the time of writing - although young forward Youssef Chermiti is closing in on a move. But more quality is needed - or it could be a long season for the Toffees.

Signing Lerma from Bournemouth in July was a good start to the window for Crystal Palace, but exciting attacking midfielder Matheus Franca is their only addition since then. However, the Brazilian is currently injured, and Palace still need to replace Wilfried Zaha.

Shocking - Wolves, Sheffield United

Wolves have secured permanent deals for Boubacar Traore and Matheus Cunha - but both those signings were arranged last season. This summer, it has been a struggle, with Matt Doherty's welcome return to Molineux their only incoming.

Wolves have lost Nathan Collins, Joao Moutinho and Ruben Neves - and continue to loan out young talents that could potentially play a part in the league. New boss Gary O'Neil has got a job on his hands, with fans furious at the ownership.

Sheffield United are another club with money troubles - and their list of potential outgoings makes for difficult reading.

Key player Iliman N'Diaye has already left for Marseille, while last season's influential loan duo James McAtee and Tommy Doyle have returned to Manchester City. Star midfielder Sander Berge is in talks with Burnley.

Manager Paul Heckingbottom has done a superb job at Bramall Lane, and is highly popular among the club's fans - if he keeps the Blades in the Premier League, he'll probably be the manager of the season.
