The Italian side were arguably the better of the two teams at Old Trafford, but it was the Red Devils who looked like they were going to secure a crucial lead going into the second leg.
An Amad Diallo goal saw the home team leading as the game headed into stoppage time, but a 93rd minute header from Simon Kjaer evaded Dean Henderson and saw the match end in a draw.
After being impressed with Milan’s performance, and with the Serie A club pinching an away goal, Scholes feels it has to be the Italians who are favourites to progress when the sides meet again next week at the San Siro.
‘Ole [Gunnar Solskjaer] said they deserved a draw, I really don’t think they did, I think they got away with one, getting the draw,’ Scholes told BT Sport.
‘We’ve seen the qualities they have as well, they’re going to get some of their better players back as well.
‘It’s in the balance but AC Milan have to be slight favourites just because of the away goals they’ve got.’
Henderson certainly should have saved the header that saw AC Milan secure the draw, but Solskjaer refused to blame his goalkeeper and instead was disappointed with the team’s performance.
‘Very disappointed to conceded with one of the last kicks of the ball, or head. That makes it harder of course, but it was always going to be going down to the second game there, anyway,’ said the Norwegian.
‘I’ve seen him [Henderson] save them, but it’s the structure that we lose. We dropped too deep and we get blocked off and they get the header on. We should have attacked the ball with the men we had there.
‘We were a bit too slow with the possession. That’s the learning we have to get into ourselves, we have to perform every single week. We’re playing against good teams. Probably a draw is a fair result.’
