Arsenal's transfer window was dominated by the signing of Swedish international Kim Kallstrom from Spartak Moscow until the end of the season.
The move for Kallstrom, 31, was made following news that Aaron Ramsey will be ruled out for six weeks with a thigh injury, as reported by The Guardian.
And the move for Kallstrom is an effort to share out some of the midfield burden carried by the likes of Mesut Ozil and Santi Cazorla.
The transfer was a surprise to many, with speculation of a move for Schalke's Julian Draxler rife, but Kallstrom has been on Arsene Wenger's radar for a number of years now, per Sami Mokbel and Craig Hope of the Daily Mail.
The midfielder, who has 108 caps for his country, was delighted following his move and said, as per the Mail report:
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.
Many had expected Arsenal to make a move for a forward given their reliance on Olivier Giroud as the season enters the home straight.
Julian Draxler was strongly linked with a move to the Emirates to join the Gunners' growing German contingent.
But The Guardian's David Hytner reported that the 20-year-old's £37 million buy-out clause proved to be a stumbling block to the move.
Arsene Wenger later dismissed the rumours, saying in his press conference that they had been created by the media.
As Arsenal welcomed Kallstrom to the Emirates, they said goodbye to Emmanuel Frimpong, a graduate of their youth academy.
Frimpong, who joins Barnsley, had struggled to break into the Gunners' starting team, making only 16 senior appearances.
