Nacho Monreal was taken off during the first half of our 3-1 win over Burnley on Saturday, forcing Unai Emery into another defensive reshuffle.
However, after the game Emery said he was optimistic the problem wouldn’t be serious.
“It’s starting to be a muscular problem and we decided to change and not take more risks with him. But I hope it’s not big and I hope he can be with us next week.
“I don’t know if he can play at Brighton, but we can play, I think, Koscielny.
“Also Mustafi is close to coming with us. We can take more injuries but we can also recover more players.”
