Joshua Zirkzee scored his first goal in Europe for Manchester United but the Red Devils were held to a draw by Real Sociedad to leave their Europa League last-16 tie in the balance.
Dutch forward Zirkzee deservedly put the visitors ahead in Spain 12 minutes into the second half with a low strike from the edge of the box that caught out home goalkeeper Alex Remiro.
But Real Sociedad equalised through a Mikel Oyarzabal penalty, awarded after a review by the video assistant referee for a handball by Bruno Fernandes.
Manchester United will feel disappointed not to have won after they dominated the game for almost an hour, with Andre Onana not having had a save to make before the hosts were given the penalty.
Fernandes had a goal-bound strike cleared off the line by Aritz Elustondo in the first half, while the United captain also sent a free-kick just wide.
But Real Sociedad’s equaliser appeared to unsettle Manchester United and Onana had to dive to his right to palm away Brais Mendez’s 25-yard curler, before Orri Oskarsson prodded wide from close range.
Oskarsson then had a chance to win it deep into add time but Onana pushed away his goalbound effort with a strong left hand.
The second leg will take place at Old Trafford on Thursday, 13 March.
