The 27-year-old defender moves to the North-East after a season at Chelsea.

He spent the second half of the campaign on loan at Werder Bremen, guaranteeing their survival with a dramatic late winner on the final day.

The Senegalese featured in our first two pre-season games this summer and now remains in the Premier League with David Moyes’s side.

Chelsea Football Club thanks Papy for his service and wishes him well for the future.
