Yes dear I agree that Real Madrid played well but they needed penalties to win and that Atlético Madrid good play despite osing. And Barcelona had tough match and seemed to relax after their opponent got red card but they were already ahead. So that is right it is exciting time to watch because all teams are playing hard and it will be interesting to see who can make it far in tournament.
Are you delirious? What penalties? Maybe you saw some post-match penalties? Mbappe scored a goal from a penalty, it's the same part of the game as a goal from a corner or a game. If Real hadn't scored like that, I'm sure they would have found another way and they would have had the reserves to accelerate, but they were happy with the score 1-0. Osasuna had virtually no chance and failed to make a single shot on target against Real Madrid.
On the one hand, we saw Osasuna playing very defensively and Real Madrid only needed 3 points, so I think excessive criticism is also inappropriate for Real Madrid in the first match. I think we should give time for all teams to even show their best performance as a whole, we shouldn't just judge from one match.
