I must admit the fact that Milan didn't have a comfortable game against Fiorentina. The statistics proves this clearly. But they still improved their effort more in the second half and got the win they wanted finally by 1-0.
Fiorentina isn't an easy team to defeat, I'm not surprised if Milan didn't really dominate the match and must struggle hard to win. But all Milan players have done a great job, they got 3 points. This result makes them on the top of Serie A standings and keeps the hope to finish the season with the title. AC Milan still has 3 remaining matches (vs Verona, vs Atalanta, vs Sassuolo). These teams are weaker than Fiorentina, in theory AC Milan should win all the matches. But Milan must be careful that they can't lose focus against weak teams since sometimes they can make a surprise.
I don't think it's a problem AC Milan can only beat Fiorentina by one goal difference, the most important thing is that AC Milan won. Because AC Milan
does need a win in every remaining match, this is to ensure that AC Milan remains in the top position. If AC Milan fails to win, there is a possibility
that Inter, who is in second place, will shift AC Milan's position. So AC Milan is not enough just to beat Fiorentina, to be able to make AC Milan win
the Serie A trophy AC Milan must at least win in the remaining 3 matches. If we look at the 3 opponents AC Milan will face, maybe only Atalanta
can make AC Milan lose points, but because Atalanta's form has also declined this season, it makes AC Milan's chance to beat Atalanta quite large.
If AC Milan is able to win the remaining 3 matches, it is certain that AC Milan can win the Serie A trophy this season.
I think the match against fiorentina was a compulsory win by Ac Milan, it gave them a edge in their league table. Looking at the top 4 table, we all know the race for the top 4 is over, as AC Milan, Intermilan, Napoli and Juventus are the four teams leading the race. On the other hand the race for the league title lies on the shoulder of this two teams AC Milan and Intermilan. Ac Milan is only two points ahead of inter, so to achieve their long time goal, they really need to be consistent in their remaining matches, cause a little mistake from them might hand inter the trophy.
