Former Manchester United defender John O'Shea has warned his ex-teammates that they face a difficult test at the Stadium of Light on Sunday.

United travel to Sunderland with the title out of their hands but they will still want to secure the win to put maximum pressure on rivals City. A win for Roberto Mancini's men will be enough to wrap up a first City title since 1968, but should they slip up at home to QPR, United will be ready to pounce.

However, the Sunderland centre-half warned United that the Black Cats will be going all out for the win.

Speaking to The Guardian, O'Shea said: "First and foremost, you want to do well for yourself and your own team, it could be a huge game for United, depending on how City do, but we want to finish with a win for our fans and we want to try to get in the top 10."

The Irish international spent 12 successful years at Old Trafford and admitted he thought United would have had the title wrapped up by now.

"You would have expected, with all their experience, they would have managed to keep that advantage so close to the end of the season," said O'Shea.

United held an eight point lead over City only a few months ago but they have seen that advantage slip away after a combination of poor performances and a string of City victories.
