What directly triggered it in that timeline was the fact that their gap between Chelsea and Arsenal in total points had not narrowed due to the 1:1 equalizer by Fulham.

The two men's quarrel developed into a physical fight. Ferguson then announced that Ronaldo's condition was not good enough and that he needed to return to his hometown in Portugal for a period of time.
