Bruno Fernandes scored his first Manchester United goal to help steer them to a 3-0 victory over relegation candidates Watford and move the Red Devils into a Champions League place.
The Portugese scored from the penalty spot in the first half before Anthony Martial and Mason Greenwood finished the job in the second half for an impressive win at Old Trafford.
Victory for Ole Gunnar Solskjaer's side moved them above Tottenham into fifth place in the Premier League which, if Man City's European ban sticks, will see them qualify for the Champions League for next season.
New signing Fernandes produced a man-of-the-match performance and won and scored the opener from the penalty spot, via a nifty skip in his run-up before slotting beyond Ben Foster.
Watford had an equaliser ruled out by VAR at the start of the season half when Troy Deeney's goal was chalked off for a handball by Craig Dawson in the build-up - and that decision visibly deflated the visitors.
Martial was almost as cool as Fernandes as he clipped in a United second, before young Greenwood again showed a flash of his brilliance with a blistering finish that smacked the underside of the crossbar on its way.
Even Odion Ighalo nearly netted a goal on his home debut against his former club, who seem to have well and truly left the Nigel Pearson honeymoon period as they endure a torrid run of form that leaves the languishing in the drop zone.
United though, remain on the up-and-up, having exacted revenge for an embarrassing defeat at Vicarage Road a couple of months ago with a win that puts them in the driving seat for the Champions League.
