West Ham chairman David Sullivan has announced Declan Rice will be sold this summer.
Rice is a target for Arsenal, Bayern Munich and Manchester United.
Asked whether the historic Europa Conference League final victory over Fiorentina was Rice's last match in a West Ham shirt, Sullivan told talkSPORT?: "I think it has to be.
"We promised him he could go. He set his heart on going. You can't ask for a man who has committed more to us this season.
"In due course, he has to get on and we have to get a replacement - or several replacements. It's not something we want to happen. We offered him 200,000-a-week 18 months ago. He turned it down.
"It's cost him 10million to stay at West Ham in that time (in lost wages). And he wants to go. You can't keep a player who doesn't want to be there."
