Wolverhampton coach Bruno Lage has revealed it will cost potential suitors £100m if he is to leave the club in the summer.
Neves is in contract talks with Wolves but has been linked with Barcelona, Liverpool and Manchester United. As reported on Thursday, Neves remains the number one target for Erik Ten Hag should the Ajax boss take over at Old Trafford this summer.
"I don't know if it's Man United or other teams, what I know is we have a special player here with us," Wolves boss Lage said ahead of his side's Premier League visit to Newcastle on Friday.
"What he is doing this season is very good. I think also the way we play, he can show a better Ruben, and also the way he plays puts our team on a different level.
"When you have that player, the best thing to do is improve his salary and years of the contract.
"But who knows, when you have a top player like him in that specific position, that can defend and attack, and is a top professional and a great man, the big teams are there with £100m to buy these kinds of players."
The 25-year-old signed a new contract in July 2018, extending until the summer of 2023.
