Trossard on for Martinelli

HT: Aston Villa 1-0 Arsenal

At least two times during the first half, most recently a few moments ago, the cameras showed Leon Bailey limping. He played on both times, but we’ll see how far he can go into the second half, if at all.

The winger has dealt with more than his fair share of injuries in his time, so Unai Emery may have to consider protecting him here.
