On Monday, Chelsea confirmed the signing of 19-year-old defender Mamadou Sarr from sister club Strasbourg for a fee of £12m on a deal running until 2033.

Mike Maignan (29) wants to complete a move to Chelsea. As per L’Équipe, the France No.1 has told AC Milan that he will not be renewing his deal with the club. There is therefore an ultimatum:

Chelsea's offer of 35m euros (£29.5m) for English winger Jamie Gittens has been rejected by Borussia Dortmund, who are demanding 50-60m euros (£42-£50m) for the 20-year-old.
