The summer window has slammed shut, and Premier League clubs are already being judged on how wisely they spent. While it is still early days, several deals stand out for value, fit and immediate impact. Here are the ten best transfers of the window. 

Bruno Guimaraes to Arsenal 

The Gunners missed out on Vinicius Junior but landed his Brazil teammate instead. A 30-minute cameo against Aston Villa already showcased the line-breaking passes Arteta’s side have long needed, while his leadership and combative edge simply add to qualities the champions already possess. 

Julio Enciso to Ipswich 

A creative South American arriving at a side expected to struggle looked risky on paper. Yet his extraordinary work rate in Paraguay’s World Cup shock over Germany, combined with two assists already this season, suggests the 22-year-old has both the talent and the appetite for a relegation scrap. 

Ayyoub Bouaddi to Manchester City 

The teenager nicknamed “Einstein” ran the show for Morocco against Brazil at the World Cup and already has a Champions League debut plus more than 60 Ligue 1 appearances. Filling Rodri’s boots is a huge task, but the young Frenchman appears completely unfazed. 

Mamadou Sangare to Brentford 

The Bees have unearthed another gem. The £41m arrival from Lens needed only one midfield masterclass against Tottenham to leave bigger clubs wondering why they let him slip. The 24-year-old Mali international looks every bit the next smart Brentford investment. 

Victor Munoz to Liverpool 

Costing under £40m from Osasuna, the flame-haired winger has already made an impression. An unused substitute during Spain’s World Cup success, he won a late penalty at Newcastle and scored on his first start against Nottingham Forest. 

Emi Martinez to Chelsea 

The clear bargain of the summer. Chelsea paid just £7.5m for one of the Premier League’s most reliable goalkeepers and a World Cup winner, finally fixing the one position they have consistently neglected during the BlueCo era. 

Thomas Meunier to Sunderland 

Arriving on a free at nearly 35, the Belgian right-back brings height, stamina and experience from his country’s golden generation. Sunderland have the structure to help veterans thrive, as Granit Xhaka proved last season. 

Mateus Fernandes to Tottenham 

Two previous Premier League campaigns ending in relegation make this an unusual pick, yet the midfielder’s calmness receiving and passing in tight spaces looks tailor-made for the chaos that often surrounds Roberto De Zerbi’s side. 

Nico Gonzalez to Newcastle 

The Spaniard slotted straight into the midfield and looked at home immediately. In the win at Tottenham, he controlled the tempo and sprayed cross-field passes with ease, giving new boss Matthias Jaissle an instant platform. 

Konstantinos Tzolakis to Hull 

The Greek goalkeeper, a club-record signing from Olympiakos, has kept two clean sheets as Hull sit on six points. Pre-season predictions of another Derby County-style disaster already look wide of the mark.
