Yes, both teams have equal chances of winning the title. PSG team was in very bad form in the first round of Champions League. But now this team is very strong and can challenge any big team. PSG won in the knockout round against strong teams like Liverpool and Arsenal. And in the matches against these two opponents we saw PSG's dominance.
Inter Milan defeated a team like Barcelona in the semi-finals. I didn't think Milan would win against Barcelona. Milan played great and they were very tactical. To win against Luis Enrique's PSG, Inzaghi will definitely have to create a smart match strategy. Both Enrique and Inzaghi are very experienced.
I liked Donnarumma's performance in the previous matches because his good performance gave PSG the chance to go further to the Final and this is an advantage for PSG because they have a goalkeeper who is so calm and makes a lot of saves. The squad owned by Luis Enrique is still quite young so they are much faster and have quite good stamina.
Inter Milan must find a way to stop PSG players because if they let PSG play more openly then PSG's chances are much greater. Inzaghi must find a special format to stop PSG's attacks because implementing a total defense strategy may not necessarily stop the movement of PSG players who are quite sharp.
