The Gunners head into their clash with Sunderland this weekend missing as many as 10 first-team members due to injuries, with Santi Cazorla the latest long-term casualty.
Alexis Sanchez is one of the names on the list - the Chile international suffering a hamstring injury during Arsenal’s 1-1 draw with Norwich City last weekend.
The former Barcelona man has had hamstring problems before, but Wenger is hopeful he will make a speedy recovery as he tells reporters that it’s usually a quick one to overcome.
“Alexis is a hamstring and usually it is quick one to recover,” Wenger explained.
“He had a four-week holiday in the summer, he was rested in some games and had all the medical signs to say he was OK to play at Norwich.”
The Arsenal boss has come in for plenty of criticism this week after fielding Sanchez despite the player carrying a slight hamstring strain from his previous matches.
The Copa America winner has played non-stop football with very little rest time for the past two-and-a-half years, due to the World Cup and Copa America falling in successive summers.
The long-distance international friendlies and 2018 World Cup South American qualifying campaign hasn’t helped, and there has been plenty of talk regarding giving Sanchez a mini winter break.
Arsenal need him back in action as soon as possible, though pushing him too far could have serious repercussions.
