He's no Ronaldinho, but the guy has determination, willingness to run his socks off, left and right footed, accuracy, and is very spatially aware. Some said Van Nistelrooy was a "goal hanger" LMAO, such basic knowledge of football. It's movement.
Muller isn't a maestro with the ball, everyone has his dog knows that, but sometimes, simplicity in football is the most deadliest of things. And T.Muller, Lahm, Kroos, Schweinstiger all do the basic stuff better than any other players. Collectively, they're efficient as ever, and why Bayern are wiping the floor with opponents.
Typical Germans.
