Milan will have a hard time against Fiorentina, but they will not lose. The league champion is now clear, but the competition with Juventus for the 2nd place continues.
My prediction is that Milan will win this game and keep the points difference with Juventus.
Ac Milan are now three points away of Juventus for second place. I believe AC Milan will not make a mistake by dropping points in any of their next game. Fiorentina is in the 8 position in the league, but they are always strong at home, AC Milan is in great form and they will win this game, despite the fact that they are playing away.
But, they don't play in any other league besides Serie A in this season, so I don't think they will underestimate or take it easily with the rest matches. Probably Inzaghi would use this moment for experiment, unknown players might play.
Inter need to think about the next generation of their strikers, currently they have 2 prime players and 2 old players, they have none young player.
You are correct, since Inter Milan did not compete in any other league but Serie A, they may not take any of their opponents lightly. Despite the fact that Inter Milan now leads the Seria A table by 14 points, they will not lose any of their games simply because they are at the top of the league. This is the greatest choice for Inter Milan; they need to lose one and focus on one. They have been eliminated from the Champions League; now it is time to make a record in the Seria A league to give their competitors a major numbers advantage. Inter Milan may use their anger at being eliminated from the Champions League against any of their opponents because it is the only trophy they have to win this season.
