Vincent Kompany needs to improve their skills, and because of that they can't relax, because it seems that the situation has changed and other teams are also getting stronger, Dortmund and Leverkusen are also still in the same zone which is always a strong challenger for Bayer Munich, they must remain aware of that if they want to win again.
When Kompany was still a player, Kompany was basically a defender and thus, at least made Kompany understand more about making a good and strong defense. Moreover, Bayern Munich has players with good quality in its main squad and thus, it is certainly a must for Kompany to be able to make Bayern Munich's defense even better to get clean sheets more often. Because if Bayern Munich is able to have a strong and good defense,then maybe it is certain that Bayern Munich will be able to dominate the Bundesliga again.
But, about other teams I think at this moment there is also nothing that looks better. Because after all, although teams like Bayer Leverkusen also won in their first match, but the fact is that they are also difficult and need greater efforts to get their first three points in the previous match. Therefore, I think at this moment it is still uncertain which team has a better chance and also, the league has just started and ofcourse there will be many bad events and result that they will get throughout this season.
While that is true, Bayern has never been a team that benefited more from their defense than from their offense. I know that the team scored loads of goals in so many seasons and sometimes the defensive performance was a point of contention. I know there is this saying that the offense wins games and the defense wins titles, but nobody wants to see a Bayern team that is overly focused on their defense. It is an important part of the game, but Leverkusen won the title with their offense last season because I argue that their opponents were so busy defending that it was hard to take the initiative for them and attack. That's why you could see it both ways.
I don't know how important it is what position Kompany played during his career. It can be a good strategy to emphasize the defense for some teams of course, like Atletico Madrid usually does it. But you see that it doesn't work as well anymore. But when you have these players like Musiala, Gnabry, Olise, Kane and Davies with his high pace, then you can't be too defensive during the game. Being very strong attackers is part of a strong defense as your defense doesn't have to do as much.
Union took the lead now, but St. Pauli has more ball possession although they can't turn that into chances. For Union it would be a great early season so far and for St. Pauli a big failure, but still one half to go.
