Let's look at the opinion of bookmakers:
Manchester city 2.85 - 35% chance of winning, City is overrated in my opinion. A title every three years in the presence of a crowd of competitors? Don't even dream, sheikhs!
Paris Saint Germain 5.55 - 18% but the second place among all contenders? That's just funny.
Bayern Munich 6.05 - in my opinion Bavaria is underestimated, even considering their current problems.
Liverpool 7.55 - 13% looks like a fair estimate, but still Liverpool is overrated.
RealMadrid 10.10 - LOL, comments are redundant.
Barcelona 11.70 - the most incomprehensible estimate in my opinion - on the one hand, only 8.5%, which can be called a modest/fair chance. On the other hand, I have not yet seen a single confirmation this season that Barcelona is ready to compete with strong clubs. Why is it fundamentally better than Tottenham (which has a coefficient of 18.9)? I do not see.
There were exactly two games where Tottenham played convincingly strong soccer. That was against Southampton and against (an extremely weak) Leicester City. They barely won against Marseille (one man down for over 45 minutes) and they lost against Sporting Lissabon. The game against Manchester City was rescheduled, which would have actually been the only game to make a first judgment.
Fc Barcelona should have won the game against Bayern. They were the better team, but Lewandowski and I think Gavi screwed it with missing their 1000% chances before Bayern took the lead by means of a corner that found the head of Hernandez.
Except for the first game in La Liga against Rayo Vallecano and the unlucky loss against Bayern, I would clearly see them ahead of Tottenham right now. That doesn't mean they would 100% win a head to head of course, but if the question now was about the odds in a game Barcelona vs. Tottenham, I would probably lean towards a 60-65% to 40-35% in favor of Barcelona. That does not perfectly reflect the difference in the odds provided, but I would definitely say Barcelona seems to be stronger than Tottenham right now.
Hmm... it's not even funny to be honest. The ability to realize moments is the same skill as any other. Bayern were stronger in this match and saying that Barcelona should have won is not serious. Just as frivolously as some still talk about the fact that Real Madrid was lucky last season.
By the way, you probably think that Barcelona should have won the Europa League last year, right?
As for comparing Barcelona and Tottenham, the point is not in their personal comparison (and by the way I'm not sure that Tottenham is weaker than Barcelona in a personal meeting), but in the fact that in order to become a champion you must defeat the rest of the competitors (and not one). I do not see a single factor that would say that Tottenham are weaker than Barcelona on average relative to other rivals, but there are such factors regarding Barcelona - for example, their inability to play against the bus and simply disciplined teams playing on the counter.
I do think that it is pretty normal to judge games with a realistic sense. What does that realistic sense look like?
Well, if we repeat the game between and Barcelona the exact same way for 100 times and we allow for some likelihoods to be applied to, for instance, Lewandowski shooting the ball across the bar from that position early on in the game, that game is taking another direction. Or Gavi failing to score out of less than 5 meters...
I am not saying that Bayern had no chance, they always have a chance as their quality is just too high to not have any chance at all. Even Muller and Neuer said after the game that there is really no reason to be overly optimistic given how the game went. Or the penalty situation with Dembele. This game a lot of things went in Bayern's favor, things that were NOT under their control. That is why I say luck was with them this time.
A standard situation turning a game upside down can always happen and it makes the sport exciting for spectators as well if a game can take an unexpected turn. A good example is Villareal against Bayern last season.
As is said in law, being right does not automatically lead to getting justice. I think I am more or less able to assess what team was better, but lacked a little bit of luck in the end. It's great that Madrid made it because that is an amazing story. And why is it so amazing? That even Kroos said this title was quite special and probably won't happen that way again? Because it won't happen again... There were so many situations that even Real Madrid didn't expect to play out in their favor for a good reason. Donnaruma throwing away the win with his spectacular failure and so on.
Saying "the team who won is the deserved winner" would definitely apply if no external actors had influence. Penalty or not for Dembele against Bayern? A lot of referees would have blown the whistle.
