Yes. Fonseca has not been able to build AC Milan into a winning machine. Milan are 10th in the Serie A table with just five points, the club's worst start since 2018. Unfortunately for coach Paulo Fonseca, AC Milan's next match is the derby della Madonnina with rivals Inter Milan. In every aspect, AC Milan are inferior. And AC Milan will probably be defeated. If that happens, the risk of coach Paulo Fonseca having to follow in the footsteps of coach Daniele De Rossi, who was recently fired by AS Roma, is very clear.
After being officially appointed as Stefano Pioli replacement, Paulo Fonseca has yet to bring Milan to a convincing performance this season. From the five official matches played (Serie A and UCL), Milan has only managed to win once, draw twice and lose twice. The directors are very worried about the current condition of the team, his career with Milan will soon end if he fails to win the Derby Della Madonnina. On the other hand, Inter Milan are in top form, they are unbeaten in their last five matches, including when they held Manchester City to a 0-0 draw in the Champions League. Looking at the performance of both teams, Milan chances of winning the Derby this time are very small.
However, I think Milan should be more patient with Fonseca. Fonseca needs time to build a team after making so many changes. Firing the coach immediately will not bring good results. The reason "Fonseca may not make good wine because his grapes are not good" I want to allude to the fact that AC Milan's current players have not met expectations. Another important element that I think AC Milan is lacking is a real leader in the squad. Since Tonali left.
Everyone involved in the team has high expectations for Milan to perform well again in the future, management will take action on what is happening to Milan now. Firing Fonseca is not a bad idea, Roma has done it before. Some great names are still available at the moment, Maurizio Sarri, Edin Terzic and Thomas Tuchel could all be good options as potential replacements for Fonseca, perhaps they could make the wine a little better with their talent and experience.
