Because Pep is genuinely intelligent, respectful and humble it makes him pretty much unflappable and immune to the kind of psychological childishness that Moureen is employing these days. The Portuguese has always relied upon his previous clubs' identities as big clubs with a history of underachievement to build up an underdog, backs to the wall culture and install himself as a hero figure that could take the club to previously unknown glories against the wishes of the establishment.
At Porto he could utilise the fact that they weren't one of the Lisbon clubs, Chelski were the nouveau riche misunderstood upstarts battling against the behemoths of the North and bigger clubs in London, Inter have a victim complex linked to their paranoia regarding more successful rivals in the North of Italy but in Spain that crap doesn't wash because he's at a club that is the very epitome of establishment. The club's battle isn't to join the establishment but to rid itself of the sense of entitlement that has afflicted consecutive teams and held them back from success in Europe, whilst at home they've had to rely on Barca committing hari-kiri and the rest of the league weakening too much to present a challenge. Moureen trying to play his default jilted anti-establishment figure just comes across as faintly ridiculous in Spain when he's managing Real Madrid, it's time he manned up.
