2. Alex Song
Perhaps in trying to solve the problem, Wenger may even go back to the Cameroonian to fix the conundrum. Signed by the Catalan club last year for
£15 million, Song has found it hard going in his attempts to get game time at the Nou Camp having only accrued 21 league appearances due to being pushed down the pecking order by more illustrious compatriots. All this could lead to new boss Gerardo Martino deeming Song surplus to Barca's requirements and possibly opening up a move to his former club. And the chance of potentially playing alongside former teammates Jack Wilshere and Mathieu Flamini let alone being managed by Wenger again, may prove to be too big a draw.
