Chelsea sign French defender Malang Sarr on a free transfer

The 21-year-old centre-back becomes Frank Lampard’s fourth signing of the summer, following deals for Ajax winger Hakim Ziyech, Leipzig striker Timo Werner and Leicester left-back Ben Chilwell.

Sarr arrives at Stamford Bridge on a free transfer after allowing his Nice contract to run down and Chelsea have confirmed that the Frenchman will spend next season on loan.
