The Arsenal striker limped out of the 2-2 draw with Everton after scoring the equaliser and could now miss the crucial meeting with Besiktas on Wednesday nightArsenal manager Arsene Wenger is sweating over an ankle injury picked up by Olivier Giroud in the 2-2 draw with Everton that could rule him out of the crucial Champions League play-off second leg.
The former Montpellier striker replaced Alexis Sanchez at half-time at Goodison Park and rescued a point with an equaliser one minute from time after Everton had initially raced into a two-goal lead.
But the 27-year-old limped off before the whistle blew and Wenger is now concerned that the forward could be an injury doubt for the Gunners's Champions League play-off meeting with Besiktas on Wednesday.
He told Sky Sports: "It is a big game on Wednesday, we hope we can recover. I hope we have not lost Giroud in the final minute. It's a stretched ankle. It doesn’t look good."
On the impact the Frenchman made after replacing Alexis, Wenger added: "I thought we would dominate the game and that we needed some physical presence and I think he had a very good second half.
"It's great for our belief to know that away from home 2-0 down that with players like that we can come back.
"We always had a good mentality, the competition in England is tough for everybody and the group is still young and improving I think we are really ambitious and we showed that again."
Arsenal take on Turkish side Besiktas on Tuesday knowing a win will be enough to take them through to the group stages of the Champions League, following a 0-0 draw in the first leg in Istanbul.
