From your comment it seems like you didnt watch liverpool this season that much, or you were picky, liverpool looks motivated vs big ones, where they have that underdog aura above them, otherwise, they are comical at blowing up 2, 3 goal leads, their defence was bad, and still is, their performance vs city few days ago was great, but their fans cant be relaxed even with 3:0 lead because they can blow it easily, they dont have stability, they are going all out and then what happens happens, teams that plays open football does suit them, so my point is valverde doesnt need to make things similar to liverpool, because barca are not underdog vs nobody, every team would counter them easily with that kind of tactic, like other teams are doing same to liverpool, and with klopp tempo players burn out easily
