Despite his disciplinary problems and failure to truly live up to his huge summer transfer fee, the Swiss international should be in the side on Sunday.
Likely to be coming up against the formidable pair of Fernandinho and Yaya Toure, the Gunners will need a little bite in the middle to ensure the talented duo do not run proceedings from the middle.
Xhaka is guaranteed a booking in this game due to its magnitude and what will be a frenetic pace, but if the player keeps his cool, then he could have a massive influence on proceedings.
Xhaka will need to marshall the middle of the park and keep tabs on the likes of Kevin De Bruyne, who given an inch of space, will punish the Arsenal defence.
Xhaka will be needed to break up play and at times slow down the pace of the game, and a big performance is needed from the player if Arsenal are to progress.
