The Premier League transfer window has once again seen eye-watering amounts of money spent by clubs looking to improve their squads ahead of the new season.

With plenty of players settling into new surroundings, there will be intrigue as to who can make the quickest impact.

Here, we pick five new signings to watch heading into the 2023-24 campaign.

Declan Rice (Arsenal)

Arsenal had to spend a club-record £105million to land England midfielder Declan Rice from London rivals West Ham.

The Gunners smashed their biggest-ever spend by over £32m as manager Mikel Arteta hopes Rice can prove a missing part of the jigsaw, with the aim to take Arsenal from runners-up to Premier League champions this season.

Rice, 24, left West Ham having lifted the Europa Conference League trophy in his final game as captain. 

It will be interesting to see if he can continue to impress at the very top level.

Moussa Diaby (Aston Villa)

Unai Emery turned Villa’s season around when he was appointed as Steven Gerrard's replacement last October.

Villa went from relegation candidates to European qualification under the Spaniard, who has now started to shape his squad for the fresh challenges.

Moussa Diaby will be a pivotal part of that process after the France winger signed from Bayer Leverkusen for a reported club-record fee of £51.9million. 

Such intent to get their man means the 24-year-old will be under immediate pressure to deliver as Emery looks to build on his first year in charge.

Dominik Szoboszlai (Liverpool)

Jurgen Klopp looked to overhaul his midfield after a disappointing season by Liverpool's – and his own – high standards last season.

James Milner, Naby Keita, Alex Oxlade-Chamberlain, Jordan Henderson and Fabinho have all departed and Hungary international Dominik Szoboszlai is the big-money addition from RB Leipzig who will be expected to fill some of the void.

The 22-year-old cost a reported £60m and hit 20 goals in 91 games at Leipzig, including getting on the scoresheet in the 2023 DFB Pokal final victory.

Andre Onana (Manchester United)

Erik ten Hag's rebuild has continued this summer as the Dutchman aims to improve on finsihing third and winning the Carabao Cup trophy in his first season at Old Trafford.

The signing of goalkeeper Andre Onana from Inter Milan is the most striking change as he replaces David De Gea – who left at the expiration of his contract – as United's first-choice, reuniting with his old Ajax boss.

His ability to play out from the back is what Ten Hag is looking to add to his defence. 

But if his pre-season games are anything to go by, there could be gains and pains as he settles in.

Sandro Tonali (Newcastle)

After sealing Champions League football for the first time in 20 years, many would have expected the deep pockets of the Saudi PIF see Eddie Howe splash the cash on plenty of new arrivals.

Instead, he has been selective with recruits and the £55m arrival of Italy international Tonali is the most eye-catching.

The defensive midfielder, 23, won the Serie A title with AC Milan in 2022 and he also has 14 senior caps in a competitive position. 

Howe will hope he can improve the steel in his side.
