Sunderland have accepted an improved offer from Stoke for Lee Cattermole, according to Sky sources.

Stoke saw one deadline-day bid knocked back but returned with a second, believed to be worth up to £5m, and the midfielder will now travel south to talk terms and undergo a medical.

Sunderland sanctioned their former captain's departure after completing the permanent signing of Brighton's Liam Bridcutt earlier on Friday.
