Arsenal have completed the signing of Swedish midfielder Kim Kallstrom on loan from Spartak Moscow until the end of the season.
The 31 year-old left a training camp in Abu Dhabi on transfer deadline day to join the Gunners after manager Arsene Wenger made it his priority to add a midfielder to his ranks in the wake of Aaron Ramsey's injury set back.
"Arsenal is an amazing club with a lot of great players and a coach who has done really well here for a long time," Kallstrom told Arsenal's official website.
"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."
Wenger added: "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."
The Gunners' boss revealed early on Friday morning that the club were targeting a midfielder after they learned they will be without Wales international Ramsey for up to six weeks after suffering a thigh injury.
The Frenchman's midfield options have suffered further hits with Jack Wilshere still struggling with an ankle injury and Mathieu Flamini facing a three match ban after picking up a straight red card against Southampton on Tuesday.
In February, the Gunners face an away trip to Anfield, the visit of Manchester United and an FA Cup fifth round tie with Brendan Rodgers' side before taking on Bayern Munich in the Champions League, and Wenger has chosen to supplement his spate of absences with the veteran Swede.
"At the moment, we need more midfielders. We are looking at the opportunities we are looking to try and bring at least one body," told a press conference Friday morning.
"We are a bit hit now by the red card of [Mathieu] Flamini, the setback of [Aaron] Ramsey, the fact that [Jack] Wilshere is not available. In an area where were had a lot of players, suddenly we are a bit short."
