David Moyes says the chance for West Ham to win a first trophy since 1980 is a "big incentive for the club" in their Europa Conference League quarter-final second leg against Gent.
They drew 1-1 in Belgium last week.
"Isn't it incredible that West Ham United are the favourites to win the Europa Conference League?" said Moyes.
"There are only three European competitions, and for people to think we're worthy of winning one of those, it means a lot."
West Ham got to last season's Europa League semi-finals, where they lost to Eintracht Frankfurt.
