I think his comments are unbelievably classless. There is a wild difference between "the way they set up made it hard for us, we were restricted to longer efforts, we had to commit extra players, and they caught us out on the break" and "they don't play proper football" he makes it sound like their win is somehow invalid.
It is disappointing that this sort of thing gets ignored when it is Klopp, considering Mourinho rightly gets hammered every time he says something arsey.
I hate the opinion that playing defensively is "anti-football". Atletico have less good players than Liverpool, if they had tried to play free flowing attacking football they would have been absolutely punished.
The only set of fans that have the right to complain about Atletico's tactics are their own fans, if they are happy to watch this type of football then they don't have to answer to anyone else
