Chelsea are reportedly close to agreeing a deal with Toulouse for French centre-back Issa Diop.
The 20-year-old, who came through the youth system at his current club before making his first-team debut in 2015, has already made 24 Ligue 1 appearances during the 2016-17 campaign.
Manchester City, Arsenal and Tottenham Hotspur have all been credited with an interest in the France Under-21 international, but according to The Mirror, Chelsea are close to agreeing a deal with Toulouse.
Diop, who was part of the France squad that landed the European Under-19 Championship in 2016, is said to favour a move to the Premier League despite interest from Italy in the shape of Parma and Roma.
It is understood that Chelsea will pay £15m to bring the centre-back to Stamford Bridge.
