Nah, I'd say exactly the opposite to be honest. One of the first things he did when he came in was to tighten up the defence and reign them in a bit. The CL final against Liverpool showed his adaptability, with him basically using the first 30 minutes to soak up the pressure and give them no space, and then gradually start to control the game. In fact, I think that's one of the reasons he was so successful in a cup competition, because he's able to adapt to the opponents. Arguably, his lack of any clear playing identity in the same way that Pep has is the reason why he's less successful in the league, where most of the time, playing your own game well against teams below you will get you results.
