Milan need to be serious to manage their playing strategy, to get 9 points from this.
That is exactly what they need to do, no more, no less, and i am pretty sure they know this, they will try to do it, but anything is still possible, the pressure is going to be on, in the three games left, the fans and the players of the both Milan clubs will feel it severely, but the players must try their best to keep their heads, and finish on a high.
For Inter, their job is simple: win all of the remaining games, and hope AC Milan make a mistake/slip up. As for Ac Milan, their job is straightforward, win their remaining games and they are champions again, after quite a very long time. I want Inter to be Champions, but if Ac Milan win it, then they deserve all the credit they can get.
