In my opinion this competition will add some extra flavor because Mbappe will be competing against his former club for the first time in the FCWC semi-final match. It goes without saying that if PSG is able to win this CWC trophy, they will win a rare big quintuple title and this rare record of theirs will be achieved in one season.
It will be a tense moment for Mbappe, as PSG fans will make sure that they remind Mbappe of the champions league trophy they have won without him. They will drag him and make the ground hostile for him. Mbappe is even lucky that this match is not being played in PSG ground if not it would have been worse. I think the match will live up to expectations as both teams are currently inform. Any team can win this match, I support both teams and I will watch the match without bias, that's the only way to enjoy the match.
