IMO the key to getting the best from our front 4 is to get the ball forward quickly, by vertical passing between the lines as opposed to hoofing it.
Against opposition that want to play high I'd be looking to release PEA asap before the space behind their defensive line closes. In this scenario Ozil needs to make himself available in space between the lines in the middle 3rd.
Against teams that sit deep we can use the flanks and look to create overloads in the final 3rd. In this scenario Ozil needs to go wide rather than stay central as it is the movement of the CAM going wide that provides the overload to draw the cover defence across.
I suspect if Ozil can get his head around the high press then we may see him in his best form going forward in the season. As it stands he is one of only 3 players to have scored more than once for us in the PL, but he's yet to register an assist.
I'd be curious to know how many of those stats came after Rambo was hooked.
