Arsenal's hunt for a new centre-back continues with Sokratis Papastathopoulos the latest defender to be linked with the club.
The Gunners have reportedly made a bid of £10.9m for the Borussia Dortmund player.
However, according to the reports, which have emanated from Italy, Dortmund value the the Greece international closer to £20m.
The two clubs have until Monday night to try and agree a deal.
Arsene Wenger has been on the search for defensive reinforcements since Thomas Vermaelen was allowed to leave for Barcelona in a £15m transfer.
The Arsenal manager spoke openly about his desire to bring in more cover, despite the exceptional start to life at the Emirates from summer signing Calum Chambers.
Kostas Manolas was another defender linked with a move to Arsenal, however he joined Roma instead.
Papastathopoulos only joined Borussia Dortmund last summer and made a total of 28 Bundesliga appearances after taking his chance after injuries to Neven Subotic and Mats Hummels.
Prior to that the 26-year-old played for Werder Bremen and before that Italian clubs AC Milan and Genoa. He has 51 caps for Greece and was a part of the World Cup squad.
