Favorites ceased to exist in football because everything have been upside-down. Watching the scene where Aston Villa nailed Bayern Munich and where Lille humbled Real Madrid still amazes me. What's happening in the current days of UEFA Champions League? It's definitely going to be really difficult and unpredictable for gamblers this time around, they have completely no dominating odds to follow because the system have been transformed, everything working zigzag and this is so not for the good of gamblers.
But in the Champions League things like this happen quite often. Even if we look at last season, we saw a surprise in the end because without our expectations we could see Dortmund reach the final even though they ultimately failed in the final. And it is possible that many surprising things will happen again this season where the competition will become fiercer with more clubs joining.
Real Madrid's defeat by Lille was very surprising and I think it was the most surprising thing this season. Which also makes us think that Real Madrid is unlikely to be able to reach the peak like last season again. But Real Madrid always rises at the right time and we have seen this quite a lot in the past.
