Bertrand Traore joined the Chelsea academy from French club Auxerre in 2013 but his progression into the first team has been slow.

The 21-year-old made the step up to the senior squad in 2014 but has been restricted to just 10 Premier League appearances since.

This season he has been on loan with Dutch side Ajax, earning valuable experience with the Europa League finalists.

And his performances are said to have attracted interest from Ligue 1 side Lyon who are lining up a summer bid.
