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.
