Barcelona may have won this game but I am certainly sure that this wasn't how they wanted it to be. Barcelona definitely wanted to rest players like Lamine Yamal, Raphina and Frankie De jong but the bad start and the first half injury for Barcelona cost them to bring in this players and the game changed.
If I was asked Hansi flick should have started his main squad and try to make the game secure and then bring the off. Let's not forget that the laliga title is also very important for Barcelona this season and they are almost there.
Valladolid, despite being relegated and one of the worst performing teams in the league, surprisingly took the lead at the beginning of the match. Although Barcelona conceded an early goal, they were not going to accept defeat before El Clasico and they needed to pull off this match to beat Valladolid and regain their confidence before the big match, and that is what they did.
Valladolid is one of the worst teams in the league, even though they scored a surprising goal, what could they do against Barcelona for the rest of the match. Well, they still showed good resistance.
