The 24-year-old is set for a big-money move to an 'ambitious' club based in the English capital, according to agent Jean-Christophe Thouvenel, although Manchester City are also in the picture.
"The discussions are very advanced with a London club," Thouvenel told setantasports.com.
"It is not West Ham, no. Tottenham? Well, I cannot reveal it to you right now.
"To give you a clue, without naming the club, their manager is not English, they are a very good club that have a very ambitious project, they want to attack well and defend well.
"A new cycle will start there and I expect a very important transfer for the player.
"I am also in contact with Manchester City's general manager."
