Bruno Fernandes’ stunning volley salvaged a point for Manchester United at struggling West Brom but Ole Gunnar Solskjaer’s side lost further ground in the Premier League title race.
United moved back above Leicester in second place, but are now seven points behind leaders Manchester City, who also have a game in hand.
The Baggies took a shock lead after just 83 seconds as on-loan striker Mbaye Diagne outmuscled Victor Lindelof to head in from Conor Gallagher’s cross.
United were finding it difficult to make inroads in a lacklustre opening period until Fernandes hooked Luke Shaw’s cross into the top corner with his weaker left foot.
The visitors improved in the second half, Mason Greenwood testing Sam Johnstone with a low strike and Scott McTominay seeing his follow up cleared off the line.
With time running out, skipper Harry Maguire leapt to send his header towards the top corner, but Johnstone tipped the effort against the post to deny United an injury-time winner.
Sam Allardyce’s side could have won it themselves late on but Diagne struck his effort over the crossbar from six yards out.
Though they claimed a draw, West Brom remain in deep trouble at the wrong end of the table, second from bottom and 12 points from safety.
