Such a shame about the injury. Most of our fixtures during this time are manageable, although Kos/Gabby lineup can be a little suspect from time to time.
Mustafi's played so much of the season, he was probably due a bit of a rest bite. As long as we don't pick up any other injuries at the back, I think we can just about manage in his absence, though certainly a big blow for our next two away games, he would've been hugely important.
At least by New Year he should be back and Per is not far away from returning either, so we'll be bolstered in numbers soon enough.
