Alex Song - Cameroon international Song has struggled to impose himself at the Camp Nou since moving from Arsenal last summer. With the Gunners evidently keen to provide adequate alternatives to the combative presence of Mathieu Flamini, a return to the Premier League leaders would appear to suit all parties.

If this is indeed the case, then long-serving boss Arsene Wenger should look no further than Borussia Monchengladbach's Ter Stegen.
Mohamed Salah - While Arsenal are certainly blessed with a plethora of gifted playmakers in the middle of the park, it is crucial that they do not lose sight of just how much of an impact can be had by fast wide players.
