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.
For a very long time I was expecting Ac Milan to be in stable and lose ground on the title race, my mind told me they would stable. In my heart I wished they could win. Inter were more consistent. But Ac Milan kept on picking important wins. I was surprised they were winning games expected of them to lose. I think Pioli has to take a lot of the credit for this triumph, especially when you consider how close the club were to hiring Ralf Rangnick in 2020, before instead electing to make the Italian's temporary contract a long-term one.
I think Inter has actually passively assisted them in winning the league title because Inter had a really good advantage over Milan and they just could not hold it. They lost crucial matches at crucial times and that certainly caused a lot of problems. But I have to say at the end of the season Milan traded reliable and obviously was the better team.
