The Belgian striker has come in for plenty of criticism for his form in the big games for the Red Devils this seasons but his goal record does not leave much room for argument.
The 24-year-old has been getting to grips with life at Old Trafford since his move to the club from Everton in the summer transfer window.
Lukaku headed home Marcus Rashford’s cross in the 27th minute at The Hawthorns as he netted his 10th goal of the season in the Premier League.
Jesse Lingard then made it 2-0 in the 35th minute, before Gareth Barry pulled one back for the home side in the 77th minute.
And former Manchester United defender Neville was clearly impressed by Lukaku’s contribution after he netted the opening goal on Sunday.
Speaking during Sky Sports‘ coverage of the game, Neville said: “It was that little breakthrough from Nemanja Matic in midfield that started the attack. Lukaku had no space at all.
“The pace is on the cross and Lukaku’s header is fantastic. He just glides it into the corner, it’s a brilliant finish.
“There is absolutely no chance for Ben Foster.”
The win left Manchester United in second place in the Premier League table and still 11 points behind leaders Manchester City after 18 games of the new campaign.
The Red Devils will return to League Cup action in midweek when they take on Bristol City in the quarter-finals.
They will then take on Leicester City in the top flight on Saturday night.
