That is no longer valid in my opinion, the match in the final will be different, as happened in the Europa League even though if we look at the overall statistics since the beginning Man United was better but in fact they lost in the final match as well as for the Champion League final match later between Inter Milan v PSG and if we look at the overall strength of the two teams now I think it is quite balanced so that both teams have the same chance of winning the title and regarding predictions and also everyone's favorites are different and that's natural.
The only thing that can have an effect is when one of the teams has an important player injured. But fortunately the two teams seem to be in a fairly even position where both still have their main strengths. Moreover, I saw at PSG that there were no injured players in their team. And that is an extraordinary thing that indicates that the team can really look after its players very well.
Meanwhile, Inter Milan actually has 3 injured players, they are
1. Valentín Carboni (Attack midfielder) - Cruciate Ligament Tear
2. Benjamin Pavard (Central defender) - Muscle fatigue
3. Piotr Zieliński (Central Midfielder) - Ankle Problem
Maybe this will have a little influence but I think Inter Milan is fine because they still have other players who are also very reliable.
