Eh, he's not that classy all the time. He's gotten in some slagging matches in the past, picked up fines for calling a referee a liar etc. His first reaction when someone got injured last year was to walk up to the medical staff and sarcastically clap in his face mid-game.
He threw a bit of a hissy fit and refused to shake hands with anyone after an MLS all star game.
He's certainly not above taking digs at other people, certainly not rival teams. His feud with Mourinho got played out in press conferences throughout 10/11 and 11/12.
And not to mention - his apology coming hot off the heels of declaring how many offered he had gotten.
Love the guy, can't wait for him to come, but he's not some silent Saint who will not comment on anything in case it causes a stir.
