Mbaye Diagne put the hosts ahead just moments after kick-off, only for Bruno Fernandes to equalise via an acrobatic effort just shy of half-time.
Player ratings from the Hawthorns.
David De Gea - 8/10: The Spaniard did what was asked of him for the most part, produced an impressive double save to deny Diagne late on.
Aaron Wan-Bissaka - 7/10: Sturdy throughout, didn’t step a foot wrong but failed to create as much as he would have hoped.
Victor Lindelöf - 6.5/10: Poor marking played a hand in West Brom’s opener, he sharpened up as the game continued.
Harry Maguire - 7/10: Unfortunate not to score a winner late on, the United captain was there when needed.
Luke Shaw - 8/10: Continued his strong run of form, registering an assist for the equaliser.
Fred - 6/10: Scuppered a couple of half-decent opportunities, failed to have any real impact.
Scott McTominay - 7/10: Another who failed to greatly impact the match, though didn’t step out of line.
Bruno Fernandes - 7.5/10: Not the sort of dominant performance we’ve become accustomed to, however, popped up with a fantastic goal.
Anthony Martial - 6/10: Quiet throughout, failed to create any clear-cut chances.
Edinson Cavani - 6/10: Never had a real foothold in the game and failed to cause any real problems for the WBA defence.
Marcus Rashford - 7/10: One of the more creative players in the side but ultimately failed to punish the opposition.
