I am very happy to welcome Napoli's victory over Fiorentina and they really deserved it. Fiorentina played quite well, but every time they got a chance they failed to score a goal. Like when they got a penalty kick but Fiorentina failed to do it and Napoli had to concede after that. Osimhen's absence doesn't seem to be a problem for Napoli and they are firmly on their way to the semifinals of the Supercoppa Italiana.
The absence of Osimhen in the team because he has to play for Nigeria in AFCON isn't a problem for Napoli, this is proven by the results of Napoli's match this time, they managed to beat Fiorentina even with a clean sheet.
BTW, regarding their journey in the Italian Super Cup, they will not go to the semifinals, because this match itself is a semifinal, their next step is to play in the final, and the opponent that awaits them next is Inter Milan or Lazio who will play tomorrow.
However, Osimhen's absence for Napoli in Serie A is clearly a problem and we know that Napoli's performance declines a lot when Osimhen is not there. It seems like coach Walter Mazzari wants his team to play better in the Italian Supercoppa because somehow they have to qualify even though their opponents are quite tough, namely Fiorentina. But unfortunately here Fiorentina can't do much and can only lament their fate if Napoli are still above them.
The other semi-final match between Inter and Lazio is certainly highly anticipated and it is curious who will qualify for the final against Napoli. Maybe if it was clear from me I would wait for Inter because they have a better attack and Lazio is only strong in defense but not good in attack. But the thing that is quite worrying is that the match will end in a draw in normal time and there I might be blind and not know who will go through extra time.
