I think Bayern Munich only needs to improve the abilities that exist now, they don't need more players, so far Bayern Munich has a very good team and is fairly solid, only if there is an injury in the main player, sometimes Bayern Munich has difficulty getting the right peng. to be able to play as usual.
You're right. They don't need new players, they have enough quality players in all lines. What they need is surely to improve the performance of the existing players. They need to maintain their good performance in each match, it is the key if they expect to win the title this season. For the injury problem, they won't be very confused because they have many alternative players.
I don't think you are just a person who feels bored with the Bundes League because Bayern Munich is a subscription to the winner of the league, but if you pay attention to every match in the Bundes League, the competition is much better, and I also see there is no comparison of the power that is far between Bayern Munich and competitors in the Bundes League. Some squads that have recently increased not only Bayern Leverkusen, but Stuttgart also experienced good improvement since the beginning of the season.
Yes, Bundesliga is more competitive now. Some teams are stronger this season, they race for the title will be tighter than the previous season. Leverkusen, Leipzig, Dortmund, and Stuttgart become tough competitors for the title. This season is interesting, I assume Bayern Munich will be difficult to win the title again.
