I think maybe
@Cnaiür urs Skiötha didn't phrase it properly but his underlying assertion does resonate with a lot of football enthusiasts.
While Guardiola is a great innovater, drawing from the philosophies of Cruyff, Bielsa, Van Gaal, Sacchi - it's fair to say he's not the most pragmatic manager or tactician around. He's a bit of a purist that believes his version of football is superior and somehow ties in with the concept playing the beautiful game in its right spirit.
Fergie was like this during the first half of his tenure - those United teams had a gung ho attitude of always being on the attack and underachieved at the hands of 'negative continental teams'. But he adapted to that and built more defensively sound, organized and disciplined teams in latter years.
Like a younger Fergie, Pep needs to learn that it's not always possible to outperform your opponents in an attacking/ possession sense, sometimes you need to rake a more agricultural route. Until he shows that side to his game, I'm afraid it's hard to argue his case vs Mourinho whose teams have the ability win despite being out of form/ lacking in personnel. For Pep's sake I hope he learnt from last season humiliation at the hands of Madrid.
