In as much as they won the game bro truth be told that was a very disappointing result, like I wasn't just expecting one goal from Real Madrid in that match, they have really spent enough funds in this transfer window to have got such poor performance, hmm I'm beginning to doubt if they can really do something this season, yes we can't judge with just a game, but at least it won't be wrong if they start the first game with a very good and impressive result, if they continue like this am afraid Barcelona will still have it this season, and again they I think they should consider the UCL too if they really want to go far they should better fix what may be the problem.
Why are you so excited right now? Do you have little knowledge about football? You don't need to be so disappointed so soon.
It should not be forgotten that there have been major changes in the team and they are not doing well. So if you think that Real Madrid will start breaking mountains immediately with the changes in the team, then you are wrong. They need to be given time to prove themselves and also to adapt to the team. Even the first match of the season does not tell the future of the season. Just start, let them finish and wait for the final result. Considering the last 5 seasons, Barcelona is playing great and has won the title in 2 of the 5 seasons. Real Madrid has also won it twice. But Barcelona seems to be stronger since last season and they are a very strong team this season as well.
