Rumoured transfer conversation. Please let it be true!
I imagine even Barca might have room for a little anxiety against a front four of Sanchez, Walcott (sub Giroud at 60), Mahrez and Ozil.
Of course, defending against the famous three at Barca is also a problem for Arsenal. Hoping the Koscielny-Gabriel combination is in place in time for the home game. Can't get away with Mertesacker against such opponents, except if Arsenal camp inside their own penalty area.
