It has been reported that Eintracht Frankfurt chief Bruno Hübner has told Lucas Piazon the Bundesliga club is the best place for him.
Everton, Arsenal and Zenit St Petersburg are also keen on the Chelsea midfielder, who is on-loan with Eintracht this season.
But Hubner said: “Lucas is going to earn more here, but first we need to, as soon as possible, talk to Chelsea.
“The Bundesliga is the right place for Lucas to develop further. It would be great if he chose us.”
Piazon is tied to Chelsea until 2017.
