Chelsea have completed the signing of teenage midfielder Lesley Ugochukwu from Rennes on a seven-year contract.

The France Under-19 international moves to Stamford Bridge for a reported transfer fee of £23.5 million (€27.3 million or $30 million) as the club continues its rebuilding under new manager Mauricio Pochettino.

19-year-old Ugochukwu made his professional debut for Rennes in 2021 and went on to play 60 times for his hometown club.

He joins Christopher Nkunku, Nicolas Jackson, and Angelo Gabriel in west London, with Axel Disasi’s transfer from Monaco expected to be finalised within the next few days.

Co-sporting directors Laurence Stewart and Paul Winstanley said: “We’re delighted Lesley is joining Chelsea. He is an impressive young player who has already made his mark in Ligue 1.

“He has a huge amount of potential and we know he is going to continue to develop and improve. We are pleased that he has joined us in the U.S and that he will be able to integrate with the squad quickly”.
