In this match, the Barcelona attack was like a bee that can't make honey. They had many goal chances but struggled to score. They conceded 2 early goals and were stressed, they couldn't score 3 goals. In a game like this it might seem good to come back and get 1 point, but Granada are one of the weakest teams in the league, so this is definitely 2 points lost for Barcelona. I think Real Madrid and Atletico Madrid won't lose points against Granada. This means that Barcelona will have to take 3 points from bigger games to make up for this loss. Like winning in El Clasico, they need to win big games without even a draw.
Lamine Yamal's performance is improving day by day. It's important to remember that this boy is still developing, he will score many more goals and assists in the future, this is a start for him. I also want to mention Sergi Roberto, a player who should get more minutes. I don't understand why Xavi isn't making enough use of him this season.
