The Swedish international agreed the move yesterday.
Arsenal fans had high expectations of the last 2014 January Transfer Window. They were particularly keen to see a new striker arrive at the club.
But what they didn’t expect is what they got … Kim Kallstrom.
The Swedish midfielder was probably not needed at the club, but Arsene Wenger was keen on bringing in the Spartak Moscow man to add some depth to the midfield, so snapped him up on loan until the end of the season.
But it was not a very successful spell at the club. Kallstrom was injured from the get-go, and a serious back injury saw him on the medics table for the majority of his stay.
So, at the end of his loan deal, Arsenal opted against making a go at a permanent move and the Swede returned to Russia for the 2014-15 campaign.
Since returning to Russia this controversial Arsenal signing, with over 100 caps for Sweden, has improved and he became a regular in the side once again.
However, his contract in the Russian capital was not renewed and yesterday his future was resolved. It was announced on their official website last night that Kallstrom would be playing in Switzerland from next season. The 32-year-old has signed a three-year deal with the club, which could see him through until retirement.
Arsenal fans will wish him all the best in his new adventure.
