Arsenal head into the winter months battling on three fronts - the Premier League, Carabao Cup, and the Europa League.

Fortunately for manager Arsene Wenger , his players have largely avoided the treatment table so far this season.

One player who is out long term is Santi Cazorla who has been absent for more than a year.

But with a hectic Christmas and New Year schedule on the horizon, Wenger will need everybody at his disposal if Arsenal are to remain in the hunt for trophies come the end of the season.

Here, our colleagues at football.london take a look at who's missing and when Gunners fans can look forward to their return...

Danny Welbeck

Injury type : Hamstring strain

Out since : Limping off in the second half against Watford on October 14.

Expected return date : Manchester City (A), on November 5.

What Wenger said : "Welbeck has a groin problem, I think it will be two to three weeks before he is back. He will not be back before the international break."

Injury type : Achilles

Out since : October 2016

Expected return date : January 2018
