Does being favorite of a particular give any team winning, haven't you seen a scenario where favourite becomes the losers at the end of the match, I have always said this, this a game of soccer and final at that matter, no should be underrated, despite that Chelsea has not improved much but to this extent I think they will fight this battle very well, Chelsea has another play pattern when it comes to the finals of competitions like this, is already today and am not giving up on Chelsea, I am happy where you said that Chelsea will be giving their best performance in this match that's to say we shouldn't be too certain that a particular team will win the match.
Chelsea might get lucky today if they play well in defense. I think this is the only thing they can count on. But considering how good PSG are in attack right now, I think they still will not be able to keep their goal safe from conceding. I expect two goals from PSG. What Chelsea will be able to answer depends entirely on them. But I think PSG will win in regular time today.
If Chelsea win this match against PSG today I we call it luck, because Chelsea can't withstand PSG in anyway, PSG performance is beyond doubt the team is operating in a higher frequency. But all the same less hold back and wait for the real game and leave arguments aside for now, maybe after the match we will come back for a new section, my bet is on PSG.
