Congrats to Milan on the win of course. However that performance wasn't convincing enough to me.

Yeah of course it is nice to have that power in you to make a comeback and win anyway.
But man, a title contender should be able to show a more satisfying efforts in such games, shouldn't they? My favourite for the title is Inter honestly. Their scoring productivity makes me believe in them more compared to others.
It is not unreasonable to expect a more consistent performance from a title contender. However I think AC Milan have shown a strong defensive ability recently which has helped them stay in the competition, even if their style of play has not always been clear. Yesterday's 3 - 2 win over Torino FC, thanks to two excellent goals from Christian Pulisic, has helped them to stay at the top of the league
So I think you are right, consistency is of paramount importance. Milans attack could sometimes falter and their defence is also somewhat weak. On the other hand your favourite team Inter Milan has already shown that they are capable of scoring a lot of goals and building strong momentum, i could say their recent 4 - 0 win over Como
Because of this, Milan can still be optimistic however if Inter maintain their attacking consistency then they will probably be slightly ahead
