I thought Inter had a very good and genuine chance of winning the league title but they lost important matches at crucial times which certainly deprived them of their League title. I am not saying that Milan did not lose any important points, they also lost some very important points but they became very consistent towards the end of the season when it mattered and that's why they are able to lift the league title.
They actually had 3 or 4 chances this season when they were at the top but indeed they failed to push the chances there because from what I see they always make some mistakes and always lose even with teams that are far below when they are at the Top standings.
This is what makes it difficult for them to get a chance to climb back up again
