Juventus and AC Milan are favorited this season. Because, Lukaku is not in Inter Milan so they will be a little behind. The AC Milan team is strong. Their team has experienced players like Giroud and Ibra. Juventus have a goal machine Ronaldo. I think they are more likely to win the title this season if Ibra is not injured.
For Juventus, I agree with you, they really have the chance to become Serie A champions this season. However, for AC Milan, maybe they don't have it. The reason is that Milan will now play in the UCL, which maybe Milan team has less time to rest, so Milan players might be experience fatigue while playing in Seire-A. I think staying in 2nd place end of season is a good position for Milan.
Juventus continues to bring in players to strengthen its squad, including Locatelli, who has just been officially introduced to the media, while on the other hand, there are still many players who are already qualified, including Ronaldo, who will be the player he relies on, I am so sure Juventus can win this season. .
Milan only signed Giround and not sure about Ibra whether he is still productive or not due to his old age.
Inter Milan is getting weaker after Lukaku is sold and not coached by Conte anymore.
