I never pay attention to pre-season games, it's not much different from the club's training sessions when the players play 11 vs. 11. Endless number of substitutions, experimental lineups, unclear motivation of the opposing team - for example, you are playing seriously, and for the other team it is just a warm-up game. How can you evaluate the result obtained? We will see the first results in the first rounds, it seems to me that a lot will be clear right away about what awaits Bayer with Ten Hag.
It is true that the results of pre-season matches are not very important. But I think pre-season matches are important. Because in these matches, coaches test their squads. And before the season starts, we get an idea of the capabilities of the squads. In pre-season matches, we often see renowned teams losing. But losing in these matches gives an idea of the weaknesses of the squad. The coach can take the necessary steps to strengthen his squad. And that is why pre-season matches are very important for clubs that make big changes in their squads.
