Jose Mourinho says Marouane Fellaini was key to Manchester United's Europa League triumph in 2017.
Mourinho won three trophies in his first season in charge at United.
He told The Telegraph: "I won a Europa League final with [long balls from] Sergio Romero to Marouane Fellaini.
"Ajax pressing but pressing oxygen because the ball was not there.
"Ball to Fellaini's chest. Play from there. Two-nil. Bring the cup home. Three titles. Disaster of a season."
