Last season's champions (Barcelona) were held to a draw by Rayo. This was certainly far from my prediction. I assumed Barcelona would win against Rayo, as their squads were clearly the best, boasting many star players. In today's bet, I bet on a Barcelona win because I saw Barcelona as the strongest. Unfortunately, my guess was wrong, and the match between Rayo and Barcelona ended in a draw.
As the home team, Rayo certainly played well, attacking Barcelona well. If I'm not mistaken, they scored numerous goals. Unfortunately, the referee only awarded one goal in this match. If all of Rayo's goals had been awarded, Rayo would have had the potential to win against Barcelona. If Yamal hadn't scored on penalties, it seemed certain Barcelona would have lost to Rayo. Fortunately, Yamal scored on a penalty kick.
Now, Hansi Flick must really improve Barcelona's game so that the Barcelona players can capitalize on the opportunities that arise.
I agree with what you said, that Barcelona shouldn't have played like this. They were far from their usual style of play, it was like they lost their game. Barcelona lacked intensity and made many mistakes that they shouldn't have made. They also argued that the Vallecas pitch were in poor form, which affected their performance, but I don't think that's a complete excuse... their game simply didn't show the quality they should have.
If Barcelona want to catch up with Real Madrid, who currently sit at the top of the table, they must fix their mistakes right away, otherwise, they can forget about the La Liga title.
