Also regarding us, I just get so pissed off whenever I see Ozil have to drop back and help transition the ball into the final third of the pitch. Because we lack great ball carriers, we are stuck often in the middle third, in the opponent's half, playing far too many passes than is necessary. I do think Cazorla greatly reduces this problem as he has a decent enough passing range but he also has deficiencies in his game which leave a lot to be desired. I think its why Cazorla and Coquelin worked well, as it was defensive enough and Cazorla could move the ball quicker than the others up to the final third where Ozil is at his most effective.
Having Ozil in the middle third is just not really utilising his strengths. I think that is what Xhaka was meant to be for, tbh, as his passing cuts out the need for all that intricate *******s whereby an opposition team can easily just press the ball away from us.
Also regarding the problem with Walcott and Chamberlain, they are good athletes but they are not good footballers. I would rather have Nasri back honestly because he had the guile of a proper Arsenal attacking player.
