Which of the academy players he managed in Chelsea, Madrid or Inter was proven to be good? No-one at all. So, who cares that he didn't give chances to players who weren't good enough. He was there to win matches, not to turn donkeys into less donkeys.
Don't even bother man, the fact that those academies didn't produce a lot of players of genuine quality should be overlooked. Folk will project one anomalous season at Chelsea over his entire career (apparently he leaves every club in the relegation zone), clubs with at times toxic broadroom and dressing room environs (Chelsea and Real Madrid with Roman and Florentino) will be used against him, but we will selectively erase Internazionale and Porto from our memories, or even Chelsea I where a lot of the players would have fallen on the sword for him; people will dig up, or even invent arguments just to have a go at Mourinho because he doesn't fit the stereotype and is too much of a *censored word*.
eg. Apparently Pep vanquished José in head to head meetings, even though:
At Internazionale, he won the European Cup against Bayern Munich, after defeating Pep's Barcelona in the semi-finals.
In his first season at Madrid, yes they lost 5-0 at the Nou Camp, and lost the league, and lost in the semi-finals of the Champions League; but they did defeat Barcelona in the finals of the Copa del Rey.
In his second season, they won the La Liga, but lost to Barcelona in the Copa del Rey.
So, in broader picture terms, and in terms of winning silverware, it was a rather even match - 1 European Cup each while facing each other in that 3 season window, 1 La Liga apiece, 1 Copa del Rey title for each, and one extra Supercopa for Pep; this despite Barcelona's superiority in terms of personnel. So the disparity in overall W/L ratio doesn't really tell the whole story.
Another one - Pep supposedly destroyed Mourinho in terms of mind-games, even though Guardiola quit immediately after José won the La Liga with Real Madrid; and seemed visibly unnerved at times through the 2011/ 2012 season - it was for a multitude of reasons to be fair, and maybe his heart wasn't in it evidenced by the sabbatical, but still, Pep snapped in the face of Mourinho's war of words:
"Señor Mourinho has permitted himself the luxury of calling me Pep, so I will call him Jose," he said. "Tomorrow at 8.45pm we face each other on the pitch. He has won the battle off the pitch. If he wants his own personal Champions League trophy away from the pitch, let him take it home and enjoy it. In this room [the Bernabéu press room] Mourinho is the f------ chief, the f------ boss. He knows all about this and I don't want to compete with him in here. I'd just like to remind him that I worked with him for four years [at Barcelona]. He knows me and I know him.

Pep says (to quote) - "He has won the battle off the pitch". But nah, Guardiola destroyed Mourinho when it came to mind games.
