Anyway, back on topic (sort of).
The idea that Ronaldo deserves better (it's understandable that he wants away), etc. Basically - he deserves CL football at this stage of his career, he shouldn't have to waste a full season playing for a non-CL team.
Okay - fine, yes.
But there is no indication whatsoever that he informed the club that he wanted out before...yes, when? He apparently had a talk with ETH which was "generally positive" at some point before pre-season.
ETH is on record saying that he had talked to Ronaldo and that he (ETH) was looking forward to working with him.
ETH was not hired (and certainly did not talk to Ronaldo) until after it became clear that United would not play in the CL this season.
So - why did this paragon of professionalism and elite mentality not announce straight away that he would be wanting a move?
My guess is this: Mendes has been on the case for months, trying to secure a deal. But Ronaldo didn't want to come out and say it (not privately either) because he didn't want to burn any bridges/piss off United prematurely. But then, as time marched on and it became increasingly clear that he wasn't that attractive (to any club he fancied), he became more desperate.
All of which is understandable - from his perspective. That is - from his personal, purely selfish perspective. But it's really hard to paint it in a positive light if you want to insist that he's either a) a stand-up guy or b) a "United legend" or c) a super professional guy whose individual goals are aligned with those of the team he happens to play for.
It would obviously have been better for United if he had made it clear from day one (that is, when it became clear that we would not play in the CL this season - i.e. months ago) that he would be pushing for a transfer.
