Sunderland live updates
Keeper Keiren Westwood is the latest man to leave Sunderland as head coach Gus Poyet re-shapes his squad.
The out-of-contract Republic of Ireland international, who missed much of last season with a shoulder injury, has become surplus to requirements at the Stadium of Light with Vito Mannone establishing himself as number one and Oscar Ustari providing the back-up since his arrival from Almeria.
Out-of-contract Sunderland defender Phil Bardsley is closing in on a move to Stoke.
Press Association Sport understands the 28-year-old Scotland international is undergoing a medical in the Potteries with a view to sealing a switch from the Stadium of Light after six and a half years.
The Black Cats had hopes to extend Bardsley's stay on Wearside after re-opening contract talks after initial discussions came to nothing, but appear to have had to admit defeat.
Sunderland skipper John O'Shea is determined not to find himself involved in a relegation battle next season.
The 33-year-old central defender led the Black Cats to safety as they staged an unlikely fightback to drag themselves out of deep trouble and preserve their place in the Premier League at the end of the last campaign.
– Sunderland captain John O'Shea.
You don't get any medals from climbing away from the foot of the table, but I was asked how the feeling we have at the moment compares with collecting a winners' medal.
Undoubtedly the elation we are all experiencing has got to be up there.
The achievement is all the more satisfying because of the teams we have had to face in recent weeks and the pressure we were under when we were written off.
We have stood up to it and, after last season, we are already thinking about making sure that next year, we start off much better so we don't find ourselves in the situation we have just come through.
