I do not think that it would be 4-0 that would be not only a bad offense but also a horrible defensive outing for Milan and I do not think that will happen, they are not that bad to let something like 4-0 happen, they are one of the top teams of serie A and definitely have enough power to fight as much as they can.

However one thing is for sure, I believe we are going to see United win tonight, even if the difference is not that much, it will still be enough for United to be easy on away game, maybe  a 2-0 game or a 3-1 game would be more possible, that way when they go to Milan they will be playing with ease and they will win go to next stage no matter what. I think betting on United to win tonight would be a great idea for everyone involved, it would help them a lot but it would be easy for us to choose them and win something as well, odds looking nice.
