West Ham fear big club interest is arriving for Manchester United and Chelsea target Dimitri Payet.
The Sun says the Hammers will rush to offer Payet new terms in a bid to fend off their league rivals.
The 28-year-old moved to Upton Park last summer on a five-year deal from Marseille.
He currently pockets £70,000-a-week but could be set for a pay boost following his stunning start to life in England.
West Ham boss Slaven Bilic said: “There is no money in the world that would persuade us to let him go.
“He is not for sale to any club - never!"
