Arsenal's Mathieu Flamini a late scratch vs. Dortmund due to thigh injury

As if Arsene Wenger needed more injury concerns...

Already without three fullbacks for today's match against Borussia Dortmund, the Arsenal boss will also be missing his only true defensive midfielder.

While the absence of the fullbacks (Calum Chambers, Nacho Monreal and Mathieu Debuchy) was widely reported - and fully expected in the case of the latter - this latest injury blow comes out of the blue for Wenger.

In Flamini's stead, Mikel Arteta will make his return to the lineup.
