Engelbert Humperdinck backing Leicester to beat Chelsea in FA Cup
Humperdinck, 75, will represent the UK at the Eurovision Song Contest in Baku, Azerbaijan in May.
He told The Sun: "My message to the team is this 'You're playing for everyone in our city, do your best and, hopefully, you'll come out on top'. Like a manager, I can't affect the result. It's down to the players."
