David Moyes believes Roy Hodgson is one of perhaps only two managers who could keep Watford in the Premier League this season.
Speaking before the two teams meet on Tuesday night, the West Ham boss named Sam Allardyce as the other coach he would back to steer the Hornets out of trouble.
Hodgson, 74, recently replaced Claudio Ranieri at Vicarage Road, with Watford currently one place and one point from safety.
'To have any level of success you have to have a huge love of the game and Roy has once again shown he has got that,' Moyes said.
