Arsenal striker Danny Welbeck is set for an extended spell on the sidelines after he was taken off on a stretcher during his side's Europa League clash away to Spartak Moscow on Thursday.

The England forward suffered an ankle injury and was carried off after just 25 minutes and was taken to hospital for treatment.

"The news is that we are going to wait - but we think it’s a serious injury," Arsenal manager Unai Emery told reporters.

"Every injury is different. This (could) be a break of something in the ankle. It's a different injury to others.

"It's a very big injury for him, for us, for all people who like and love him as a person."
