Chelsea have been linked with a move for Southampton defender Virgil van Dijk this summer.
The 25-year-old has impressed for Southampton since moving there from Celtic.
Manchester City and Liverpool are also interested and various reports claim Southampton would demand £60 million for the defender.
Former Premier League player Danny Mills doesn’t believe Van Dijk is worth that much as he is yet to play for a top club.
“The Premier League is awash with so much money it does start to cause problems,” Mills told BBC Radio 5 Live.
“He’s a great defender and if he goes to a better team training day in and day out with better players, playing alongside better players, possibly a slightly better coach as well, he will get better.
“But £50m or £60m is ridiculous.”
Fellow pundit Kris Boyd also agreed with Mills.
“It was difficult to judge him playing in Scotland because it was that easy for him,” Boyd added.
“He’s been fantastic. Will he move? For that kind of money, obviously Southampton would sell him.
“I think he’s a fantastic player, he will make a team better, but we go back to the figure £50m-£60m for a central defender, it’s crazy money.”
