West Ham remain confident of keeping Declan Rice despite missing out on Champions League qualification.
David Moyes's side were eliminated by Eintracht Frankfurt at the semi-final stage of the Europa League, which was West Ham's last route into the Champions League as they cannot finish fourth in the Premier League.
Manchester United are long-time admirers of Rice, 23, and had identified him as their prime midfield target during provisional recruitment meetings early this season. United have been emboldened by Rice's interest in joining the club since he requested feedback from Harry Maguire and Luke Shaw while on England duty last year.
