4. A Great Midfield Battle
The strongest area of both of these teams is their midfield and the likelihood is, particularly on current form, that this is the area in which the game is likely to be won. Gareth Bale, Theo Walcott, Moussa Dembele, Santi Cazorla, Scott Parker, Aaron Ramsey, Lewis Holtby, Mikel Arteta, Gylfi Sigurdsson, Jack Wilshere, Aaron Lennon and Abou Diaby (the latter of which may be injured for the big game)... the talent amongst the North Londoner's respective midfielders is almost unrivalled and there are some incredibly interesting battles to be had. If any magic is going to unlock either defence, it's probably going to come from the middle of the park and it's going to be interesting to see which midfield comes out on top.
