Arsenal want former defender Matthew Upson to return to the club to help ease their defensive woes.
Gunners boss Arsene Wenger is keen to bring the West Ham United man back to the Emirates as he continues to experience injury troubles within his defensive ranks but is only prepared to pay £500,000.
Hammers would clearly want more than that, indicating that Sunderland are still a strong chances of luring the England international to the Stadium of Light.
