Yes, Milan benefited from referees.
You know that if a foul happens in the box it's a PK? You know that if a team has 100 PKs in a row and someone fouls them in the box it's still PK?
I personally don't think of it as who benefited more from refs, since it's a totally stupid pov, I see it as who is trying to blame their shortcomings on refs, and both team have done that.
Refs aren't perfect, so when you bitch about refs you either imply corruption, or bad luck. That's why Galliani was so furious after Muntari goal, because Juve was obviously stating that FIGC is favoring Milan and Milan can't let that type of thinking spread among people.
And @Tranquerista, dude read my posts before replying.
What is Allegri supposed to say when press members ask him about Muntari goal every week?
