Things are looking good for Arsenal on the injury front, with both Bukayo Saka and Oleksandr Zinchenko taking a full part in training on Wednesday.
It’s unlikely that either player will start against Zurich, but they could be on the bench.
Mohamed Elneny also comes into contention having been training for the past couple of weeks following his hamstring injury, which has kept him sidelined since August.
Emile Smith Rowe (groin) is still out, as is Matt Turner (groin), with Aaron Ramsdale expected to start once again.
Arsenal will be without Granit Xhaka for the match as the midfielder is suspended having picked up two yellow cards during the previous group-stage games.
