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.
A pre-season friendly match is clearly not a serious match and of course all the players usually don't always play at full strength because if they play at full strength then the risk of injury is potentially large if the players play at full strength and of course in a pre-season match it can certainly be called a match. trials for a coach to create strategies for playing second-tier players and practice making strategies and breakthroughs in preparation for real matches such as in the domestic league or UCL.
Indeed, I also saw Hansi Flick, he was very good and the players adapted very quickly to him and of course we deserve to applaud Flick because he can make Barcelona good and in yesterday's Elclasico match he was really great at arranging strategy. but yes, of course, if for example Real Madrid could take advantage of opportunities well of course the result of the match would be different but what is clear is that Real Madrid was not too serious in that match but I saw in yesterday's match we could see that Flick's strategy was very good and Ancelotti also learned a valuable lesson because of course Ancelotti can see Real Madrid's shortcomings that must be corrected.
but honestly, I am very happy to see the Elclasico match and of course I want to see the next Elclasico match in Laliga which will definitely be more exciting.
