The ever-present midfielder has played a key role in West Ham's European bid and is yet to miss a single minute of Premier League football for the ninth-placed Hammers this term.
The England international remained at the London Stadium over the summer after interest from Chelsea ended up going nowhere, but Man United manager Ole Gunnar Solskjaer is now said to be keen on a deal for West Ham's lynchpin.
However, Moyes has insisted that neither team has touched base with West Ham over a deal, telling Amazon Prime Video: "They're not true, we've had no contact from either of those clubs regarding Declan and we wouldn't want any anyway.
"He's doing great for us, he's a big leader now, he's taken a lot of the weight off Mark Noble. He's turning out to be a really good player but also a really good boy and good around the club."
Rice remains under contract at the London Stadium until the end of the 2023-24 season, where he has already made 129 appearances having just turned 22. body check tags ::
