Ozil definitely looks more solid than he was last season, which should help him with tussles for the ball and keeping the ball under pressure.
I remember reading a stat earlier this season (pretty sure after his injury) that stated Ozil had played about half a dozen games with Walcott in total so far, which is crazy as those two would benefit the most from each other's games.
Having a fully fit Ramsey, Walcott and Sanchez must have Ozil licking his lips. Not to mention the pace of Welbeck and the Ox too... Plenty of players that make runs, so no more Ozil looking up to see stagnant players wanting the ball passed to their feet.
