The final was good, in my subjective opinion Juventus looked better and they deserved to win. But these two dubious penalties ruined the whole game. In any case, congratulations Inter with winning the final! Inter had a good season and deserved trophies. For Juventus, the season turned out to be a complete failure, it’s good that at least they will play in the Champions League next season.
Winning and losing is a consequence of a match. It won't always benefit either team because strategy, players, and luck can benefit a team that may not seem worthy of winning. Of course I don't think Inter didn't deserve to win the Coppa Italia, but 2 penalties for them probably did too much for the title.
Now Inter will certainly be very positive to return to focus on Serie A, they will host Cagliari at the start of next week and I think they will be very motivated to win it. Maybe the Serie A title will still be difficult for Inter to achieve if Milan manages to win the match at home to Atalanta this weekend.
