Actually i didn't expect some of the results i saw in the champions league this mid week, the overturning of victory happening in the way we least expected is something i didn't expect, having bigger and experienced teams loosing to smaller and almost not experienced champions league teams. Madrid and Arsenal were the worse as i least expected they were going to loose at all a draw would have been a fair consideration but a loss got me wondering as it wasn't expected at all. Barcelona's consistency is such that is deserving of every applaud as they look very promising this season.
Arsenal didn't play badly, they were good enough and maybe they were just unlucky in the match. They will accept the result. But for Madrid, well we are now seeing how other teams finally know how to beat the team that dominates the UCL. Seeing that Milan were not really the favorites in the match, but beyond all predictions it really surprised us.
Anyway, we have to accept it even though we have to lose the bet and maybe not accept or not believe the result. Football always gives surprises, no team is truly invincible.
What happened to arsenal was indeed quite tragic in the match especially since the defeat was actually quite controversial due to the referee's decision to give a penalty which was deemed inappropriate, because indeed Merino's hand was not moving at all, while Yann Sommer who failed to catch the ball and punched Merino head did not get a penalty for arsenal, Although I am not an arsenal fan, but I see if arsenal was indeed robbed by the referee in the match as said by arteta, but apart from the existing controversy of course arsenal still need to improve their current performance, especially when facing a team team that has a solid defence precisly they have difficulty scoring goals.
This season UCL often presents surprises for us, we can see how teams like munich, madrid, PSG and even manchester city have experienced current defeats from teams weaker than them, so this shows if the change in the UCL format has had a significant impact on the chances of the favourite teams, so far madrid is considered the ruler of Europe and it is very reasonable given their consistency in winning trophies, but this season it seems they are really in bad condition and phase both in the league and UCL.
