That is according to club legend John Terry, who was speaking about the club's need for a new central midfielder in the spring.
Rice is starring with England at the winter World Cup in Qatar, with the Three Lions top of their group at present.
Terry told Astro SuperSport in April: “I'm going to get in trouble here for what I say! You know what, Dec obviously loves Chelsea – I think everyone knows that. I think the rejection he had from Chelsea has really helped his career actually.
“For me, looking from the outside, unless West Ham go and make a big statement in the summer and go and spend £100 million plus and say, 'We want to keep Dec and we want to bring in top players like you,' - then I think he's got a decision to make.
"I think if West Ham go and spend huge amounts of money, bring in top players, then I think it's difficult for him to walk away."
