Simeone doesn't play negative or boring football. Just because a side is difficult to beat doesn't make their football ugly. His Atletico side play their game according to who they're facing. But his philosophy is based on a solid defence which for me is a basis for great attacking football. We have players that are great going forward. Someone like Simeone will change the mentality of the team. Make them street smart and get them working hard for each other. The solidarity and mentality Arsene always "talks" about will actually be evident.
