The development of a philosophy for the whole club is a really important step. I think, I know, where Ralph got this idea from. It was Ralf Rangnick, who implemented this system in the Red Bull world. Starting with the youth teams, FC Liefering, FC Salzburg. Salzburg won the youth champions league playing the unique football of Ralf Rangnick.
I think, Hasenhüttl is inspired a lot of this Rangnick Pressing-Football, but he tries to improve it in many ways. And he is open minded and not stubborn, he make a step back, if he see, that he had made a step to much forward. Southhampton is a lot more than a one trick pony in the meantime. And this make it difficult to calculate.
