Luiz Diaz made a very good move that I think he'll surely look back and be glad he did. At Liverpool, Mohammed Salah is the main main and with the arrival of Florian Wirtz and Hugo Etitike, Luiz Diaz would've probably been a regular on the bench but with this switch to Bayern Munich, he'll still be getting playing time while competing in biggest club competitions. Playing alongside Harry Kane in the attacking line of Bayern Munich, Luiz Diaz I think can form a good partnership with the England national team captain. With the arrival of the Colombian to Munich, I think it's now almost certain that the Bavarians will defend the German title next season.
I also think Bayern Munich will most likely successfully defend the trophy next season. Leverkusen, their strongest rivals, are currently undergoing a transition period, and Ten Hag will undoubtedly need time to find balance within his squad. Dortmund looked to be improving slightly last season, but I don't think they're strong enough to break Bayern Munich dominance. The signing of Luiz Diaz will further sharpen Kompany attack, he made the right decision by joining the Allianz Arena.
Given the changes made by the Bundesliga teams for next season, I don't think anyone doubts Bayern Munich's ability to defend their title. Indeed, none of the top Bundesliga teams have made significant changes to match Bayern Munich's strength.
Their success in acquiring Luiz Diaz certainly has the potential to significantly sharpen Bayern's attack. He is a highly qualified player, and the decision to join Bayern is certainly the right one for him, as he desires more playing time.
It's a norm for Bayern to defend the title next season and I don't see it as a big deal, because they have been the favorite for long apart from last two seasons that Leverkusen won it. Kompnay should focus more on UCL, because that's where the glory lies. Bayern in the past are fierce when it comes to UCL.
Diaz is an additional advantage to Bayern and he will definitely add more value to the team's performance next season. I don't see any club that's capable of challenging Bayern next season.
