In football, you will discover that as some were celebrating, the opposite may applies to others, playing football is now what we can fully have confidence that a club most surely wins except we see the way they have been performing as the match began, while if not at the end of the match, we can't be sure of we are right or wrong about our assumption on a team in playing, all we only see is the result, whereby one wins against the other.
Everyone can be confident in a club when they've seen the performance of their players and their past achievements. This can lead to our confidence growing, even though we might eventually lose our confidence for various reasons. Because in the Champions League, there are always unexpected surprises from teams that many people might not have previously believed in, but they ultimately win by a significant number of goals. And this season's Champions League will be even more competitive, as some teams have undergone changes to their squads.
