Tierney injury update as Arsenal manager Mikel Arteta coy on return timeline after ‘op went well’

Mikel Arteta has refused to put a timeline on Kieran Tierney’s injury return.

Kieran Tierney headed back to Arsenal following international friendlies for Scotland with a knee issue.

The defender underwent surgery and revealed it “went well” but Arteta still couldn’t predict exactly when his full-back would return to action.

The Spaniard left it open-ended in terms of his club football but, with Scotland ready for summer crunch ties for World Cup qualification, Arteta also couldn’t rule him in or out for those games.

“It is a little bit ambiguous but he has a significant injury,” the manager said.

“We’ll have to keep assessing him but he will be out for some weeks.

“It’s an area where he’s had a previous injury and he felt it straight away and he’s not fit.

“Our responsibility is to look after them (players) when they’re here.

“Once they go on international duty in this case it’s the job and responsibility of Steve Clarke to decide a team he believes is the best to win the games.

“We have to try and have good communication with national teams, we have, but these things happen.”

On potentially ruling him out for Scotland Arteta added: “I don’t know, he’s just had surgery yesterday so it’s very early to understand how everything is going to develop.

“If he’s going to be out the period we estimate or not, what condition he’ll be after that period it’s too soon to say something like that.

“I think the player has to do the maximum he can to be in the best possible condition as quickly as possible.

“I’m sure Kieran will do that and once he’s there we’ll see if he’s able to compete under what kind of risk or not.

“But I’m sure he will do that.”
