No Angel, he's a prize bell and an extremely bitter man.
From his point of view he's already a world class manager and left a club he loved in Porto to work for a massive club like Chelsea where he could implement his own ideas. He got it wrong, and was sacked and it's something he has never recovered from. Packed up his life to be sacked in 6 months and is hated in Oporto because of it.
Chelsea weren't loyal to him, but he was hardly loyal to Academia, Porto or even Chelsea now.
He has never been able to get over Mourinho denying him the opportunity to coach the team when at Inter and because of it he seems dead cert on surpassing him. He went to Porto, he then went to Chelsea but unlike Jose he failed so had to prove his worth at another PL club. If he succeeds, he'll be off to Real/Barca quicker than you can blink.
I had huge sympathy with him when he was sacked and wished him all the best especially when I heard the story about sleeping in Cobham overnight but that ended with his incessant rants and attacks about our club.
There's a saying "Don't wash your dirty laundry in public", that applies to him.
