Arsenal v Bayern Munich: five key battles, including Mesut Ozil vs Philipp Lahm

Mario Goetze v Mathieu Flamini

In the absence of the suspended Mikel Arteta, Mathieu Flamini is arguably Arsenal’s most important player. The Frenchman will be charged with protecting the back four and ensuring Bayern lack time and space in midfield. The visitors have a plethora of midfield options but their main creator-in-chief is likely to be summer signing Mario Goetze. The German international is deadly when arriving late in box and with the ball at his feet outside it, so Flamini will have to stay alert at all times. Crucially, it is important the Arsenal man avoids an early booking or his ability to deal with Bayern’s threat with be compromised.
