Not necessarily decisive?
Milan have Novara on the last day. Meaning they will get 3 points there. I'm also 100 % sure they will beat Atalanta tonight. Then there's the Inter derby, which could go either way, but I think Milan will win it.
Tonight's match is HUGE. If we don't win tonight, we MUST win our last 2 games. No more room for errors. A terrible situation to be in.
