The more I watch the first goal (counter) Milan scored the more I think that 2-3 of Udinese's players had a bet against their team

It just isn't possible a Milan team that hardly walked to score such a goal. From the way every Udinese player went forward in the box for the corner, to how they tracked back and watched the ball, all the way to Handanovic's reaction.
Fuck Udinese. Just watch how they played the counters today. Milan won without expecting to win at all. Hell, I doubt that Milan even expected a draw.
