David Moyes has sent a warning to Chelsea over their pursuit of Declan Rice in the transfer window.
The Blues have snapped up six players this summer as Frank Lampard plots an overhaul of the squad.
Timo Werner, Hakim Ziyech, Ben Chilwell, Thiago Silva, Malang Sarr, and Kai Havertz have all joined for just over £200m.
But Chelsea are not done yet and Lampard still has eyes on a goalkeeper and Rice.
The latter has been chased all year but West Ham have always maintained that the England international is not for sale.
However, that stance may soften as the weeks go by with the Hammers desperate for cash.
And though an official bid has yet to be made, Lampard will be desperate to land his man.
But Moyes has issued a warning to the Blues, insisting that he wants to build his team around Rice.
The Scotsman said: “The big challenge is to get that mentality throughout the team — but Declan Rice was one who carried it. We see Declan in the Mark Noble mould.

"I want a team with a younger profile."
West Ham have come under fire after selling hot prospect Grady Diangana to West Brom, with club captain Mark Noble even speaking out.
Diangana, though, is clearly excited about a return to the Hawthorns.
“I learned a lot over the last 12 months. It was a learning process and I shocked myself (with how well I did)," he said.
“I’m looking forward to pushing on and improving more. I know I can bring more to the game and to the team.
“I’m still young and last year was like my first season in senior football. I feel I am only going to get better. I believe in the style of football we play under Slaven.
“West Ham was all I had known before last season and I’m sure people will understand that I felt some sadness at leaving.
“But coming here having had that season we have just experienced, there were no nerves about leaving at all. Knowing the manager and the players and the feelings I have got for the club just made me excited.”
