Apart from Inter Milan needing a win to maintain their position at the top of the standings, on the other hand, AC Milan also really needs a win to improve their position in the standings. So once again this will be a very hot match and will be spiced up with some very hot dramas in my opinion. In Serie A or in Italy, this derby is one of the biggest of the other derbies. The fans will be carried away by the atmosphere, the rivalry between them is very high. Maybe if this was in another league, it would be the same as El Clasico in La Liga for example.
It is a crucial match for both teams, and they both need all three points to increase their confidence on the table. I don't want be one sided, but I think that Inter should be able to win this match to keep themselves on track in title race. If not Napoli will be of more advantage than them. On the one hand, Milan would be a hard nut to crack for Inter, because Milan is also a tough team.
Well, this will be a match that will be very useful for other teams, such as Napoli that you mentioned for example. Because if Inter Milan loses this match, they will be more comfortable at the top of the standings. Also, teams like Atalanta will also use this to reduce their distance with Inter Milan in the standings.
It should also be remembered that every time a team competes, the other teams will pay close attention and they are prepared to take advantage of the situation if the team that is their competitor cannot get maximum results from the match. This must also be considered so that they do not lose their spirit.
