Its been clear that Ronaldo has been trying to manoeuvre a way out of Old Trafford since pre-season, but this interview - from the snippets - won't do anything bar speed up his retirement from football. Unless he's willing to take a big paycut (he won't - he still thinks he's one of the best players in Europe at the age of 37) he's got very few clubs available to him which meets his ambitions of playing at least another season in the Champions League, and they'll baulk at signing him, especially with this attitude. And those clubs which could see past all of that would probably be reluctant to play him as he isn't blessed with pace anymore and he doesn't have the work-ethic of (say) Ryan Giggs when he was playing in his late 30s.
Still, there's still one rich basket-case of a club which would probably still sign him - PSG.
