The Spanish midfielder came down with a calf injury in Arsenal's 2-0 win over Borussia Dortmund on Wednesday, with the club's manager fearing the worse.

Arsenal boss Arsene Wenger was left in sorrow after seeing club captain Mikel Arteta succumb to injury in the north London side's 2-0 win over Bourssia Dortmund in the Champions League on Wednesday.

The Spaniard was substituted in the 67th minute upon request, unable to see out the remainder of the game, with the French manager later revealing his knock to be damage to the calf, claiming the 32-year-old “will be out for a while”.

"That doesn’t look good, it’s the calf," Arsene told Sky Sports. "It’s very difficult to take on the chin because we are going into many games and you need everybody available, but I think Arteta will be out for a while.

Much to Le Prof's worst fears, Arsenal's injury woes continue to pile on. The FA Cup holders are still without German playmaker Mesut Ozil, who is out with a serious knee injury, whilst Jack Wilshere could miss up to four months of actions, with the English due to see a specialist over his injury.

The clash with Jurgen Klopp's crew, at the Emirates Stadium, saw the Gunners come out victorious, securing progression to the round of 16, with top spot still up for grabs.

An early goal from young French forward Yaya Sanogo, after 72 seconds of play, gave Arsenal the lead from the get-go, with Chilean star Alexis Sanchez adding the second through a brilliantly curved strike in the 57th minute.

Wenger was quick to praise his 21-year-old former Auxerre striker, though, whilst also tipping his hat off to his defense, who after a string of terrible displays, performed well and remained solid throughout the 90 minutes, keeping their first clean sheet on the European stage.

"I liked what he did tonight because we decided to go long to him and he protected very well the ball, what he did on the first goal was class, his link-up play with Cazorla, but unfortunately he got injured.

"Wilshere sees a specialist tomorrow, finally, and we will know more tomorrow night. The specialist will decide [if he needs an operation]."

"The focus [pleased me most]. Defending well together. We had a similar game to Saturday, we had to focus really well not to give any chances away and overall it was a committed game and maybe we were defensively better tonight.”
