Honestly, I don't think Pep is the reason Maureen has been left behind. It's more that "big clubs" playing like small clubs is no longer some shock tactic that teams aren't prepared for. That was Jose's thing, his one trick, playing like a lower league team but with players who have more quality so take their chances. But now there are plenty of managers who do that, so teams have figured out how to deal with it and there is nothing "special" about what he's doing anymore. His inability to evolve has seen him be left behind.
