In a few hours there will be a semifinal match in the Italian Supercoppa between Napoli v Fiorentina and yes, even though this is a semifinal match, to be honest I not have a good prediction to determine which team will win this match. Because after all, Fiorentina in their last match in Serie A also played badly against Udinese and at the same time or at this moment, at least Napoli is also in a bad trend. Moreover, Osimhen is also currently playing for the Nigerian national team which is currently taking place in the Africa Cup of Nations between Ivory Coast v Nigeria.
Although you said you are not a good predictor of games, even with the preview of the previous game that Fiorentina played against Udinese, it is not the same team as Napoli, and Osimhen is actually trying his possible best for Napoli, and his absence in the match won’t guarantee that they will lose the game. Although the game is still ongoing, you can still see for your eyes that Napoli are trying their possible best to win the game.
With considerations like that, at least there is no definite guarantee for Napoli and Fiorentina to win within 90 minutes. But indeed, considering that at this moment Napoli is not completely good compared to Fiorentina then yes, at least Fiorentina still has a good chance of winning. But still, regarding the final score I might be more confident about under goal result, because it doesn't look like there will be many goals scored in this match.
You have confidence in your prediction when you also know for yourself that you are not a good predictor, although believing in yourself is also good. You are also using the previous performances of both teams, with each team are actually trying their best to win the game. Although the game is still ongoing with a score of 1-0, Luckily enough, Napoli are presently winning, and from the performance, both teams are doing their best, but we still watch till the end and see the winner.
