Wolves boss Mick McCarthy insists Matt Jarvis and Kevin Doyle are not for sale.
Both players are interesting bigger clubs.
But McCarthy said: "If someone wants to try and take Matt and Kevin off us, any of our top stars, it is not going to be easy for them - and they are going to be expensive.
"That's not saying they are for sale. They are not for sale.
"But neither was Cristiano Ronaldo a couple of years ago, neither were Fernando Torres and Andy Carroll this season - but £50 million and £35 million changed that a little bit!"
