Arsenal January signing Kim Kallstrom could be back in action ahead of schedule.

The Mirror says Kallstrom has begun his rehabilitation - with a little bit of help from Sven Goran Eriksson.

Kallstrom has visited Leif Sward, who was England's team doctor during Eriksson's time as manager, and been to Gothenburg's Ortho Centre clinic in his native Sweden.

Arsenal's medical staff identified Kallstrom's back problem before Arsene Wenger signed the Spartak Moscow midfielder on loan last month, and the 31-year-old will complete his rehabilitation at the club's Hertfordshire training base.

The Gunners are hopeful he could be back quicker than the initial six-week estimate.
