>>149129388That's a nonsense argument. Manchester Utd was as dominant in the Premier League at the time that Ronaldo played there (and for a decade before that) as Bayern is in the Bundesliga now. And you can't discount Barcelona's La Liga titles easily when the main competition in La Liga was the goddamn Real Madrid where Ronaldo was playing. It was a direct competition between the two.
At UCL, Messi and Ronaldo went head to head twice, once with Ronaldo playing in ManUtd, once with him playing in RM. Messi won both times.
