Manchester United is in control of their last-32 Europa League tie against Real Sociedad after a commanding 4-0 victory in this relocated match in Turin.
In the opening two minutes, both sides should have scored in an open first half, and Alex Remiro later saved a point-blank shot by Marcus Rashford.
However, when Remiro missed a bouncing ball over the top he gifted United the lead in the 27th minute, ran into two of his defenders, and left Bruno Fernandes with a tap-in.
As Fernandes combined with Daniel James to tuck his second of the night into the far corner, United doubled their advantage in the second half. Marcus Rashford then made it three a few minutes later after running clear from a Fred through-ball, before James scored the fourth in the final minute of normal time.
The second leg of the tie will be at Old Trafford next Thursday.
