Turan made a name for himself in Madrid winning every domestic and European title bar the Champions League – although he was part of the team that reached the final.
The 28-year-old left Madrid for Barcelona on a five year deal over the summer transfer window ending a brilliant spell at Atleti.
The Turkish international winger is not however, able to play for his new club until the turn of the year due to the FIFA transfer ban in place.
Barcelona are appealing the decision and may be able to register Turan for action after the international break.
The bearded winger is currently on international duty with Turkey where the transfer ban does not apply.
