The only similar thing is their stage of decline
Keane was offering his opinion as a pundit for MUTV. But we all know now, Fergie as he often did knew he had to go, then he used it as means to just get him out. According to players who were there what he said it wasn't that bad. Nobody knows what he really said because the tapes were "destroyed".
Ronaldo has gone beyond the club and done a shit on a stick interview with a one of the biggest shit stirring cnuts out there who also happens to be his "friend" and who somehow has a massive audience to pedal this shite to.
From what I've seen of this it looks very calculated, is probably scripted and designed to force the club to act and either sell him to whoever will have him for nothing or release him.
Personally, I'd leave him to rot in the reserves for the rest of his contract, fine him 2 weeks wages everytime he's late or doesn't show up. He can then suck it up and do a Bogarde until June.
