Roma.
The Turkish international has been frequently linked with a move to the Premier League, with Everton and Tottenham Hotspur reportedly keen for his signature.
Last month, a report from Turkish newspaper Gunes (translated by Daily Mail) claimed that Spurs manager Jose Mourinho wants to sign the 22-year-old winger if they book a place in the Champions League next season.
Everton made an attempt to sign the exciting winger from Roma in January, and had a bid in the region of £37 million rejected by the Serie A giants.
