The top 10 most expensive Premier League transfers of the window thus far

Midfielder Morgan Rogers signed for Chelsea from Aston Villa in a record £117 million deal.

The Premier League's spending power has once again been on full display this transfer window, with clubs committing hundreds of millions of pounds to assembling their squads ahead of the new season that kicked off on Friday night.

Chelsea, Manchester City and Tottenham have been among the biggest spenders, with the Blues' £117m (about R2.56bn) acquisition of Morgan Rogers and City's £116m deal for Elliot Anderson currently topping the list of completed transfers.

Spurs have also been particularly aggressive under Roberto De Zerbi, spending £100m (about R2.19bn) on Sandro Tonali and £85m (about R1.86bn) on Mateus Fernandes.

Spurs could soon add another blockbuster signing, with Savinho's proposed move from Manchester City worth up to £85m.

The selling clubs have benefited too. Aston Villa have cashed in on Rogers, Nottingham Forest on Anderson, while Newcastle United have generated substantial income from Tonali, Bruno Guimarães and Anthony Gordon. City could also bank a sizeable profit on Savinho, following the sales of Tijjani Reijnders and Rodri.

The Financial Times reported this week that Premier League clubs had spent about £2.3bn, with Chelsea leading the way.

Here are the 10 most expensive completed Premier League transfers so far:

Chelsea broke the British transfer record to sign Rogers from Aston Villa. The 23-year-old England international scored 31 goals in 125 appearances for Villa and offers power, versatility and attacking quality. The huge fee, however, means expectations will be enormous at Stamford Bridge.

City paid £116m for Anderson after his outstanding season at Forest and emergence as an England international. The 23-year-old became the second-most expensive British player and is viewed as a major addition to a midfield undergoing significant reconstruction.

Tottenham smashed their transfer record to sign Tonali from Newcastle for a fee that could reach £100m. The Italy international brings technical quality, defensive bite and Champions League experience to De Zerbi's midfield, while his departure represents another huge Newcastle sale.

Fernandes joined Spurs from relegated West Ham for a reported £85m. The 21-year-old Portuguese midfielder impressed despite his club's relegation and attracted interest from several leading clubs. Tottenham believe he can become a key part of their midfield alongside Tonali.

Arsenal strengthened their midfield with Brazil international Guimarães, who established himself as one of the Premier League's finest midfielders at Newcastle. His £75m move gives Mikel Arteta another technically gifted and physically combative option in the centre of the pitch alongside Declan Rice.

Liverpool invested £60m in French centre-back Jacquet as they continue to refresh their squad. The 21-year-old arrives from Rennes with a reputation as one of France's brightest defensive prospects and is viewed as a long-term addition to the backline.
