The pressing tactics of Pirlo is a bullshit tactic. Team plays pressings well like Liverpool or City is all pressing on opponent center back by their striker and two winger. They also commit many small tactical fouls to break up their opponent's flow pattern. With Pirlo and Juve, Ronaldo can not press all the times, it is understandable as he is 35 now. So Pirlo makes the midfielder to press opponent CB, so leaving a huge hole in the midfield for opponent to find space. That is tactical suicide.
