Usually every team that starts the season will first look for their best form of play, because they have rested too long and there are also changes in the composition of the players, whether significant or not, but still the changes will affect their appearance, that is if we look at it from the team's side itself.
When we look at it from the opposing team they face, they must also have changed, either weakening or getting stronger, it will also greatly affect the match. How many matches have we seen that have different results in each season from the same 2 teams. That shows that there is indeed change, not only in teams that are considered weak, but strong teams will also feel the same thing.
Leverkusen have already felt the effects of the change of season, after a long break and changes in the line-up causing their performance to dip slightly. Those who performed brilliantly last season without suffering a single defeat actually performed differently at the start of this season, their first defeat was just suffered when they hosted Leipzig at their headquarters. In fact, the best opportunity to find the best form of play is when they play friendly matches, so that the coach can find the best tactics and strategies when the new season starts. Changes in performance can happen to any team when entering a new season, teams that finished in the top four last season will try to strengthen their squad in the transfer market with the aim of being able to compete with the defending champions.
Changes in performance will make the competition more competitive or vice versa, but what is happening in the Bundesliga at the moment is actually leading to positive things. Bayern Munich who failed last season, have strengthened their squad to win back the Bundesliga trophy, Leipzig are also starting to show an improvement in their performance, Stuttgart and Dortmund will be ready to provide a surprise. The increasingly solid competition will present an increasingly exciting match, Leverkusen must try to return to its best form if it wants to win the trophy for the second time in a row.
