Ross Barkley v Mathieu Flamini
The young England wonderkid could very well be the difference between two sides with seemingly very little to separate them going into this eagerly anticipated last-eight clash, at least on paper that is.
And it is for that reason that the north London club’s vastly experienced manager Arsene Wenger is more than likely to try to keep a close eye on Barkely at all times of this clash, so much so that do not be surprised to see the home team’s former France international close to the attacking starlet every time he picks up possession of the ball.
