I really liked Barcelona in the friendly match played against Real Madrid yesterday. I think they are playing very well and this is a very important plus because the manager has changed. The team seems to be adapting to Flick's tactics. Flick has made a positive contribution to the team. Now it is time for the transfers of Nico Williams and Olmo. If both of them come, they will take Barcelona to the next level.
I actually do not take the results of preseason friendly games serious because of the fact that players most times do not give their best in other to avoid being injured but if there's anything I agree with your submission about Barcelona's performance in their El Classico game against Real Madrid last night, it's part that you highlighted how they're playing to the tactics and style of the club's new manager Hansi Flick. The players like you rightly said are adapting too fast and that's good development for the club as they continue to prepare for next season.
That being said, I'm still very much convinced that the current Real Madrid team will not lose to Barcelona if that game if last night was a competitive one.
