What’s the latest on Laurent Koscielny and Sead Kolasinac?

Our captain received prolonged treatment after receiving a kick late in the second half against Bournemouth, while the Bosnia international came off.

Unai Emery had this to say about them both after the game:

on Koscielny...

I hope all it is, is one kick. We have three days between today and Saturday and I hope he can be okay.

on Xhaka and Kolasinac...

Yes he is [Xhaka] okay, he was rested. Kolasinac has been having a problem in his muscle and sometimes he is telling us to rest some matches and some minutes. The first half he finished it well, but in the dressing room he was saying he can continue, but he was feeling some pain. He could continue but I preferred to change him for a rest and also he played on Sunday with a big intensity, and today I think we could do this change and carry on with another player in this match.
