No I disagree with you on this one, because those who beted on Chelsea to win in the final between them and PSG was not lucky, why because most of them who bet on Chelsea saw it coming, even myself I saw it coming but I doubted my instinct, why because PSG was in good form, so for that reason I changed my mind and bet on PSG to win, but they lost which really broke my heart.
They had belief in Chelsea and wanted to bet on Chelsea, that's all. I am sure no one can surely know that Chelsea or PSG will win that match. Life is unpredictable and sport matches are always unpredictable too so there are chances of winning and losing with any bet.
See one thing you should know is that Chelsea doesn't joke with finals, they always put in their best no matter the team they are playing with. Beside Chelsea performance last season wasn't that bad, at least they played well last season that's was why they made it to final. Many people underrated Chelsea in that final, so what Chelsea did was to clear their doubts and they even cleaned my doubt too. So let stop saying that Chelsea won PSG by luck, because Chelsea plaid very well in that final.
No clubs want to play a final match and lose it as if they consider that competition or tournament is not important, they would have used a squad B and lost in earlier matches than a final one.
Chelsea and PSG both wanted to win the final and take FIFA Club World Cup trophy but Chelsea played better and got the winning and trophy eventually. PSG did not play good enough to beat Chelsea and they had to accept this big defeat. If they meet Chelsea again, perhaps they can perform better and beat this opponent. It's about their future remeet while we don't know will they meet each other in Champions League next season.
