The French publication report that the London rivals had representatives at the Parc des Princes last night to watch on as the 20 year old helped Toulouse keep a clean sheet in a 0-0 stalemate against Paris Saint-Germain.
Diop is one of France’s hottest young properties and has been tipped for a senior call up to the French national team. He currently has four caps for the French Under 21 side and has also won the Under 19 European Championships last year with France.
So far this campaign, Diop has made 20 appearances in all competitions, scoring two goals. He did miss six games earlier this season with a back injury but he has been a regular first team starter under manager Pascal Dupraz, playing as a centre back, since making his debut back in November 2015.
