Arsenal have confirmed the signing of Swedish midfielder Kim Kallstrom on loan for the remainder of the season from Russian side Spartak Moscow.

The 31-year-old passed his medical at Arsenal's training ground earlier today. The Gunners manager Arsene Wenger's hand was forced into the market with the news that Aaron Ramsey will be out for another six weeks with a thigh injury.

Kallstrom comes with immense experience and a short-term deal is more preferable to the Premier League side.

Wenger said: “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, himself, added:"Arsenal is an amazing club with a lot of great players and a coach who has done really well here for a long time. 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.”

Arsenal - January transfer targets 1/18 Julian Draxler - Another player who Arsenal don't have a desperate need for but have constantly been linked with. There is certainly no denying the quality of the German youngster but a January move seems unlikely as Arsenal need to strengthen elsewhere. Getty Images 2/18 Karim Benzema - Wenger is a long time admirer of Real Madrid's French striker, although he would not be a cheap option. He is also a player it seems unlikely that the Spanish giants would happily part with. Then again you might have thought the same thing about Mesut Ozil. Getty Images Getty Images 3/18 Andrea Ranocchia - Out of favour at the San Siro, Arsenal would probably face stiff competition from Man United and Chelsea if they moved for the highly-rated Italian defender. Getty Images Getty Images 4/18 Konstantinos Mitroglou - The Olympiakos forward is in red hot form and could well provide reasonably priced support for Olivier Giroud. Currently playing alongside Arsenal loanee Joel Campbell which could count in Wenger's favour. Getty Images Getty Images 5/18 Hakan Calhanoglu - Arsenal couldn't buy another attacking midfielder could they? Well rumour has it they are very keen on Hamburg's Turkish star Calhanoglu. Getty Images Getty Images 6/18 Winston Reid - While a West Ham defender from New Zealand might sound an unlikely target for Arsenal, their defence is a serious injury away from looking a little threadbare and Reid could provide value-for-money cover at the back. Getty Images 7/18 Xabi Alonso - While the free transfer of Mathieu Flamini has helped, Arsenal still look a little lightweight in the centre of the park. The cultured Alonso would certainly improve things. Getty Images 8/18 Ilkay Gundogan - Another luxury purchase for the Gunners and with interest from other Premier League clubs and Arsenal's more pressing needs in other areas of the pitch, it seems an unlikely move. Getty Images 9/18 Antonio Sanabria - Arsenal are rumoured to already have a deal in place bringing the Paraguayan starlet to the club from Barcelona. If so then they have secured themselves a fantastic player. Getty Images 10/18 Javier Hernandez - With Hernandez seemingly growing increasingly frustrated with a lack of first team opportunities at Man United, Arsenal could pounce for the proven Premier League goalscorer. It does however seem unlikely that Moyes would sell to a rival. Getty Images 11/18 Kurt Zouma - Wanted by London rivals Chelsea as well, Zouma is a highly-rated young defender who could provide some much needed cover. Can Wenger get the better of Mourinho in the transfer market this time? Getty Images 12/18 Youssouf Mulumbu - An experienced Premier League player who would add a bit of oomph to Arsenal's midfield. The surprising recent sacking of West Brom manager Steve Clarke might also encourage Mulumbu. Getty Images 13/18 Cheikhou Kouyate - Wenger has tried to sign the imposing defender in two separate transfer windows but with Anderlecht now ready to sell, this January could be a case of third time lucky. Getty Images 14/18 Ciprian Marica - Another forward linked with a switch to the Emirates, the Romanian could provide a cheaper alternative to some of the bigger names Arsenal are rumoured to be pursuing. Getty Images 15/18 Alvaro Morata - The young Real Madrid forward has been linked with a January loan move although he has stated a desire to stay in the Spanish capital. Getty Images 16/18 Alexandre Pato - Linked with Arsenal once again, the Brazilian would be a surprise choice given his relatively modest recent performances since returning to play in his homeland. Getty Images 17/18 Edin Dzeko - Despite scoring fairly consistently in his time at the club, there is a feeling that Dzeko somehow doesn't quite fit and he struggles to hold down a first team place as a consequence. A move to Arsenal would surely give him more playing time but it seems unlikely City would sell to a rival. Getty Images 18/18 Dimitar Berbatov - The former Manchester United striker is reportedly keen to move on from Fulham.
