Arda Turan
Barcelona are already looking to offload Turan after less than a year at the club according to recent reports. He has failed to break into the team after a move last summer that saw him wait until February to officially pull on the Barcelona kit due to a transfer ban.
Limited opportunities due to the presence of Messi, Neymar, and Suarez will have frustrated Turan and may even force him to seek opportunities elsewhere.
The Turkish winger has been linked to the premier league for quite some time and with United struggling offensively in the past, the addition of another creative attacking midfielder would bring many positives.
