Arsenal vs Chelsea live updates: Premier League match team news, predictions, more

Chelsea’s window was a success, with their squad now stronger than at the start of the summer. Emiliano Martinez is an upgrade on Robert Sanchez and can mentor long-term prospect Mike Penders too.

Maxence Lacroix is one of the ‘ready-made’ acquisitions and has settled quickly in central defence. Chelsea broke the record for a British player by buying Morgan Rogers from Aston Villa.

It is early days, but with the manner in which he is combining with Cole Palmer and Joao Pedro, Chelsea have one of the best attacks in the division. The club have often been accused of lacking leaders and experience.

Along with Martinez, this has been addressed with the acquisitions of Jordan Henderson and Danny Welbeck. Emmanuel Emegha and Welbeck provide backup for Joao Pedro, but the Brazilian is crucial to the way they play.

There are questions over the strength of depth in midfield. But with Marco Palestra from Atalanta bought to operate primarily as a right wing-back, captain Reece James is seen as the player to fill the spot vacated by Enzo Fernandez.

Valentin Barco and Henderson have been added to the mix, along with Moises Caicedo and Romeo Lavia. Chelsea have also retained their crown as the highest sellers in the Premier League.

Fernandez made it clear he wanted to leave, but they got a joint-highest Premier League fee of £125m from Manchester City. Making a profit on an individual signed for £106m is good going.
