I reckon Pep has said that because he is smart enough to not make it about him. You make it about the club, then it's bigger. You make it about yourself, then yuou run the risk of looking petty and thin skinned. I'm not surprised he requested an apology to the club. I'd have done the same. That gets the club, the fans, and the media on your side. As for Sleuk's ramblings, in fairness he said 'big personality.' This doesn't mean great players. Some great players don't have big personalities. Silva for example doesn't. Superb player but he doesn't have that edge. Kompany does. Balotelli with his max potential and minimum perfromance, did. Joe did. Lescott didn't. It has little to do with talent, talent helps it come out more, but some players have that and others don't have it at such levels sometimes.
But I doubt players are busy taking offense to an agent saying Pep doesn't like working with big personalities. And then inferring from that that the agent is suggesting they don't have big personalities.
