The defender gained plenty of experience during his time in Italy as he made 21 appearances in Serie A as Milan finished second, while he was also heavily involved in their Europa League campaign, during which he played against United.
Dalot demonstrated his versatility by featuring at right-back and left-back, and stressed that he has improved tactically.

However, 22-year-old remains unaware of where he will be playing next season. Dalot refused to rule out the possibility of a return to Milan.
Speaking to La Gazzetta dello Sport, Dalot said: ‘I like to become more and more complete.
‘The Italians love football, they always talk about it and being part of this culture has been a fantastic experience. And on the pitch, I feel I have improved a lot tactically.
‘There are some defensive aspects I learned here and it was fantastic to develop these qualities too.
It isn’t clear if Dalot will be part of Ole Gunnar Solskjaer’s plans after his loan at AC Milan
Dalot has played 35 times for United but had to go on loan in order to gain further experience
‘That’s not the only thing either, as I improved in pressing high and recovering the ball as soon as possible. Very useful stuff. I say that I had a fantastic year and met beautiful people.
‘It was a real pleasure to play for Milan but now I think about the Euros and I really don’t know (on his future) what will happen.’
Having progressed through the ranks at Porto before breaking into the first-team, Dalot signed for United in 2018 for £19m.
So far Dalot has made 35 appearances for United, scoring once, but he must now wait to see whether he will be part of Ole Gunnar Solskjaer’s plans for next season.
The Portugal Under-21 international has two years remaining on his contract at Old Trafford.
For now Dalot’s focus will be on the U21 European Championship, with Portugal set to face Italy in the quarter-finals on Monday.
