West Ham United have reportedly told Chelsea they must pay £100m if they wish to sign Declan Rice this summer.
The Blues have been linked with a move for the 22-year-old throughout this summer, having released him from their academy at the age of 14.
However, David Moyes is not willing to let Rice go easily, and as a result he has placed a big price tag on the midfielder, who has three years left on his contract at the London Stadium.
The Athletic states that Thomas Tuchel is an admirer of Rice, but that Chelsea are yet to open negotiations with West Ham over a possible move.
If the Blues do make a bid, they could offer striker Tammy Abraham, who is valued at around £40m, as part of the fee.
Manchester United are also said to be keen on signing Rice, but will likely be put off by the price tag after they spent £73m on Jadon Sancho.
Rice has made 145 appearances for West Ham since breaking into the team four years ago, and started all seven of England's games at this summer's European Championship as they got to the final.
