Odion Ighalo made his long-anticipated home debut for Manchester United as a second-half substitute in the 3-0 thrashing of former club Watford on Sunday.
The Nigerian striker was introduced for French striker Anthony Martial for the third game in a row with 10 minutes left to play at Old Trafford.
United were already three goals to the good courtesy of Bruno Fernandes’ first for the club from the spot, Martial’s insouciant finish and Mason Greenwood’s scorcher of a third.
Ighalo could have added a fourth when he latched on to a misplaced backpass but his goalbound shot was deflected to the post after he had rounded Ben Foster in goal for Watford.
The win leaves United three points off Chelsea in fourth place with the Reds sitting fifth with 41 points after 27 games.
Ighalo will be hoping to impress home fans and finally get off the mark for the Red Devils when they host Club Brugge in the second-leg of their Europa League round of 32 tie on Thursday.
Both sides had played out a 1-1 draw in the first-leg in Belgium.
