Arsenal are expected to move for Germany World Cup winner Mats Hummels in January - with Borussia Dortmund fearing the centre-back is ready to leave.

Hummels is valued at £30million and is also a target for Manchester United but sources in Germany believe the player would prefer a move to the Emirates.

Gunners boss Arsene Wenger is desperate to sign a central defender in the mid-season window, with cheaper options such as Aston Villa’s Ron Vlaar and Celtic’s Virgil Van Dijk also on his radar.

But, as first revealed in Sunday Mirror Sport in August, Wenger has asked to be kept informed of any developments regarding 25-year-old Hummels, who is is currently sidelined by a foot injury.

United remain interested in the German defender but are more likely to tie up a deal for Vlaar.
