Lyon have announced the signing of Chelsea attacker Bertrand Traore for €10million on a five-year contract.

The 21-year-old — who last year helped Ajax reach the Europa League final having joined on a season-long loan deal — leaves Stamford Bridge having been pushed down the pecking order under Antonio Conte.

Burkina Faso international Traore made his Blues debut in 2015 and went on to make 16 starts in the 2015-16 season under Jose Mourinho, scoring four goals.

The fee paid for Traore also includes a 15 per cent sell on clause for Chelsea should Lyon decide to cash in on the striker in the future. Mourinho's sacking and the arrival of Michy Batshuayi saw him pushed out of contention under Conte, and he was sent on loan to Ajax to gain further experience.
