Napoli have entered the race to sign Benjamin Pavard from Stuttgart.
He is already wanted by the likes of Bayern Munich and Tottenham.
Stuttgarter Nachrichten suggests that a 35 million euro offer would be needed to secure the player's signature.
Pavard starred for France in the World Cup, but chose to stay at his club for another season.
The 22-year-old right back has 13 appearances in the Bundesliga this season.
