If building a team with a clear idea of what its coach wants to achieve is the question, even LvG did better. Mourinho's achievements are better, I suppose (winning the Europa League, finishing second), but he has a far better set of players at his disposal (that is down to LvG for signing poorly). It was clear to see what he was trying to achieve with the players, and they actually looked comfortable passing the ball, which is not something that can be said of the team at the moment. In contrast, I still--after 2 and a bit years--have no idea of what type of team we are: possession-oriented / counter-attacking / high aggression? (def not the last one haha).
I broadly agree with @O's assessment of a hypothetical Guardiola squad.
