What a wreck of a post. I can imagine Ronaldo doing it, as he's done it before, directly blaming his team-mates for losses is one example.
What he thought was his potential? He was getting close to 20 assists a season when he was playing in his preferred position and not plagued by injuries or lack of game time.
Was nominated for the Ballon D'or, has won player of the year for us, was along with Berbatov the only reason we made it through the early parts of that title winning season, amongst other things. His potential was never in question, but it's obvious your opinion is plagued by your opinion of him as an individual, so carry on.
