Premier League clubs spent a record 2.36 billion ($2.97bn) on new players in the transfer window that closed on Friday, according to analysis from Deloitte.

The summer window, which was open from June 14 to Sept. 1, exceeded last year's record 1.92bn, with the top-flight clubs spending 255 million on deadline day alone, it said.

Premier League clubs were responsible for 48% of the spending across Europe's top five leagues including LaLiga, Serie A, Bundesliga and Ligue 1.

"A second successive summer of record spending by Premier League clubs suggests that year-on-year revenue growth could return following the pandemic," Tim Bridge, lead partner in Deloitte's Sports Business Group, said in a statement.

"Nearly three-quarters of Premier League clubs [14] spent more this summer than the last, reflecting the increased intensity of competition.

Chelsea have spent more than $1bn in transfer fees since the new ownership led by American Todd Boehly and Clearlake Capital completed their takeover of the club in May 2022.

The London-based club broke the British transfer record for the second time in a year by signing Ecuador midfielder Moisés Caicedo for a reported 115m, eclipsing the 106m they paid to sign midfielder Enzo Fernández in January.

Champions Manchester City signed midfielder Matheus Nunes for 53m this week, having earlier bought Jérémy Doku for 55m, defender Joško Gvardiol for 77m and midfielder Mateo Kovačić for 25m.

Last season's runners-up Arsenal splashed out 65m on forward Kai Havertz, followed by 105m on England midfielder Declan Rice, and Manchester United spent 72m on striker Rasmus Højlund.

Newcastle United, who finished fourth last season, brought in midfielder Sandro Tonali for 55m and winger Harvey Barnes for 38m.

Nottingham Forest, who finished 16th last season, signed as many as seven players on deadline day.

According to the report, almost half of the transfer fees received by Premier League clubs from overseas came from the Saudi Pro League club, which has the fourth-highest transfer spend of any league globally.

"The emergence of more active participants in the global transfer market has the potential to accelerate clubs' efforts to establish financially sustainable business models," said Calum Ross, assistant director in Deloitte's Sports Business Group.
