Francis Coquelin (RB)
With Bellerin out, Carl Jenkinson is the obvious choice to replace him.
However, without much game time under his belt, combined with the magnitude of the game, and of course it being away from the Emirates, starting this game could pose a high risk for Arsenal.
So, I would like to see, just for this game, Coquelin at right-back. The French midfielder has played in this position before and did a substantial job.
