An exasperated Sunderland boss Steve Bruce has challenged Liverpool counterpart Rafael Benitez to make a move over his pursuit of Kenwyne Jones. There has been repeated speculation on Merseyside that Bruce will allow the Trinidad and Tobago international to join the struggling Reds on loan before completing a permanent move during the summer.

He said: "Kenwyne Jones is not going to go on loan to anybody for the help of Liverpool or anybody else. I would be mad.

"Now, if Liverpool are going to come and offer an amount of money, then we all know what happens.

"Every player - every player - has got a price and a valuation. I have to say though, it would have to be a huge amount of money for us even to contemplate it with a week to go in the transfer window.

"The only thing it's done is unsettle the boy. It's got him probably in a situation where he thinks I don't want him, which is far from the case.

"But I can't stop it. Publicly or privately, I can't stop this constant thing of Kenwyne Jones every day."

Bruce was at a loss to explain a story which simply refuses to go away.

He said: "I have said - and I try to be as honest as I can - everybody in football has got a price, whether you are Ronaldo or Kaka or Kenwyne Jones.

"Now if Liverpool are serious - which I don't know if they are or whether it is Rafa having games with his board, I don't know - but the ones who are suffering from it are Sunderland and Kenwyne Jones.

"This notion that I'm going to let him go on loan, people must look at that and think I have lost my marbles.

"I may not be very good at the minute after being beaten 7-2, but I haven't lost my marbles totally, that's for sure."

Bruce's admission that Jones has his price, however, is not necessarily an invitation to Liverpool.

He added: "I haven't even got a price because I don't think Liverpool can go there.

"It's like me asking for Steven Gerrard on loan - I'll try, maybe.

"It's hugely disrespectful."
