Blackburn Rovers legend Colin Hendry says Junior Hoilett holds all the cards in new contract talks.
Having lost Phil Jones to Manchester United in the summer for a now bargain price of £16million, due to a similar clause, Rovers fans will fear Hoilett going the same way - but former defender Hendry insists the club have no choice but to agree to his terms.
He told the Lancashire Telegraph: "Rovers did have their fingers burned over the price for Jones because he has already shown he is worth a lot more and you can understand fans will be worried the same could happen over Junior.
"Hoilett is so far down the line in terms of his current contract though that the club have little option but to agree to a clause if that is what the player wants. Because otherwise they could lose him for a lot less come the summer.
"The key is to make sure that trigger price is good business. Then if one of the big clubs come in for him then you just have to accept it is inevitable the player will leave, but at least you get good money for him.
"The changes that have been made at the club have been part of the problem because opinions have changed about players as different people come in.
"We are at the stage now that if Hoilett wants a clause in his contract then the club can't do anything about it."
