Arsene Wenger is weighing up a £12million move for Borussia Dortmund's Greek defender Sokratis Papastathopoulos.

The 26-year-old centre half has been offered to the Gunners and they are trying to negotiate a cut-price deal, as Dortmund want £20m for him.

Arsenal boss Wenger is desperate for a defender after selling Thomas Vermaelen to Barcelona for £15m as he needs cover at centre-half.

Papastathopoulos - commonly known as Sokratis - is surplus to requirements at Dortmund, where Neven Subotic and Mats Hummels are the first-choice centre-backs, and the deal could get the green light.

Arsenal are also monitoring developments on Paris Saint-Germain midfielder Adrien Rabiot, but are a long way apart on a fee. PSG are demanding close to £20m for the 19-year-old and the Londoners are facing competition from clubs in Italy. It now seems unlikely they will make a big name signing in defensive midfield.

Wenger has rejected several offers of deals for strikers that have been put into the club after Olivier Giroud was ruled out until the New Year because of a broken tibia.

The Arsenal boss has insisted that he is happy with Alexis Sanchez, Yaya Sanogo, Joel Campbell, Lukas Podolski and the returning Theo Walcott.
