West Ham United manager David Moyes believes that Declan Rice is worth more than £150m amid reported interest from a number of top Premier League clubs.
The 23-year-old has been strongly linked with both Chelsea and Manchester United for some time, while Manchester City have also been credited with an interest.
One report has claimed that the Hammers have placed a £150m price tag on the England international; however, Moyes insists that the midfielder is not for sale and believes his valuation is much higher.
"The first thing to say is that he is not for sale," Moyes told BBC Sport.
"But if you are interested, it will be north of [£150m], because £100m was cheap last summer and £150m just now would be minimum – but he is not for sale."
Moyes also spoke about Tottenham Hotspur's reluctance to let Harry Kane join Man City last summer and believes West Ham will take a similar stance to ensure that Rice remains in East London.
"I look at what Tottenham did with Harry Kane, albeit it in a different way," the Scotsman added. "They said, 'no, there is a price and if someone wants to pay the price, then we'd probably do it. If they don't then he's not going anywhere'. That's it, they have kept him.
"In many ways, the football clubs are the people in charge, they've got the contracts.
"There will be times when players have got the power, but at the moment we have got Declan on the best part of a three-and-a-half-year contract – just like Tottenham have got Harry Kane on a contract and they control what happens."
Rice, who is under contract at the London Stadium until June 2024, has made a total of 183 appearances for West Ham across all competitions and has also featured 29 times for the England national team.
