Wolves boss Stale Solbakken admits he's reluctant to lose Steven Fletcher.
Sunderland and Aston Villa are keen on the Scot.
Solbakken desperately wants to hang on to his star forward but acknowledges that things could be taken out of his hands, saying: "Everybody at Wolves wants to keep him but even Lionel Messi has a price.
"At the moment he is a Wolves player and we are planning with him.
"He has three years on his contract - that's how we are looking at it.
"We are looking at targets all the time but you don't replace Fletcher overnight. That is impossible."
