Arsenal have confirmed the loan signing of Spartak Moscow midfielder Kim Kallstrom.
The Sweden international, 31, will stay with the Gunners until the end of the 2013/14 campaign.
Arsenal manager Arsene Wenger was forced to dip into the transfer market for another midfielder after it was confirmed that Aaron Ramsey will miss the next four to six weeks with a thigh injury.
Kallstrom, who previously played for Rennes and Lyon in Ligue 1, has made 108 appearances for Sweden – and will be an experienced back-up option for the Gunners ahead the season's most pivotal months.
Wenger told Arsenal's official website: “Kim Kallstrom is a hugely-experienced player. He is a midfielder with proven quality at both club and international level. We welcome Kim to Arsenal.”
Kallstrom, meanwhile, expressed his delight after completing his move.
“Arsenal is an amazing club with a lot of great players and a coach who has done really well here for a long time," he said. "I am so pleased to come here to learn as much as possible. I’m here to do my best for Arsenal and to help out the team, so we can achieve good results for the last part of the season.”
The left-footed midfielder could make his Arsenal debut during Sunday's Premier League clash against Crystal Palace.
After that, the Gunners face the toughest run of their season so far: with fixtures against Liverpool, Manchester United and Bayern Munich all on the horizon.
