Sunderland boss Steve Bruce reckons striker Kenwyne Jones on his day is worth £40million. The Black Cats boss does not want to sell the 25-year-old Trinidad & Tobago star after Birmingham and Stoke reportedly showed interest in the player.

Bruce told the Daily Mail: "Everybody's got their price, whether you're Steven Gerrard or Cristiano Ronaldo, and if something out there blows your brains.

"But with no disrespect to Stoke or Birmingham, can they afford him? I very much doubt it. It's not just the fee but wages, all the rest of it. I just can't see it.

"On his day, you can look at Kenwyne and say he's worth £40m, then on another day you'll think, 'Come on'. That's Kenwyne.

"He tests your skills as a manager. He's a big, genuine, nice lad. It's always the challenge - to get the best out of him."
