Look I'm not trying to be a dick, as everyone knows the club hasn't been doing so well and I know it's a United forum so it's difficult for people to be as objetive as they can. I don't even agree entirely with that Ronaldo said, nor I think what he's doing is the most professional behavior. For me it appears he's trying to force a move by putting a club in a difficult position.
He used to behave like that at Real Madrid whenever he wanted a pay raise or something, he would start whinning, acted annoyed, etc. Zidane would tell Florentino to deal with him and eventually the club drew a line. I don't know what he has been promised or what exactly his deal is but I do believe United need to deal swiftly with this and either get him in line or get rid of him.
With that being said I've also noticed people were hating on him since last season and have repeated constantly how United was 2nd place and he disrupted everything good with the team. To me that's a blatant lie and a clear agenda on him, although I have to say it's clear the team is trying to play a more modern styl now with ETH and there is a tangible improvement and direction now with or without Ronaldo.
