Wouldn't be surprised if we go back to the 4-1-4-1 which we were using earlier on this season for this. Arteta - Ramsey - Wilshere in the middle, Ramsey's been very poor this season but Wenger doesn't seem to want to drop him. Don't want to see Flamini anywhere near that starting 11, he's really been exposed for the average player he is in the last few weeks.
Sanchez and Welbeck alternating between the left and upfront then either Cazorla or Chamberlain on the right wing, hopefully the Ox who atleast going forward has looked really promising lately.
Will most likely be Chambers Mertersacker Monreal and Gibbs. He might bring our young right back Bellerin in to deal with the pace of Di Maria and Shaw down the left hand side and move Chambers to centre back but I'm not convinced he will do that. Mertersacker simply has to step up, him and Ramsey have been the two most dissapointing players this season.
I think this will be the first interesting game between both sides in a long time.
