Real Madrid are unbeaten in La Liga if Cristiano Ronaldo scores. The Portuguese has scored in 78 league matches, of which the Whites have won 75 and drawn three. In his first season, his team won all of the 19 matches in which he scored, while in the other three seasons Real Madrid have drawn one match in each campaign: in 2010/11 he scored in 18 of the matches that he played, in 2011/12 in 27 and the current season he has scored in 14. Also, Real Madrid have won all 15 of the official matches in which Cristiano has scored from a free kick.
A Cristiano Ronaldo goal in the League means that Real Madrid will not lose that match. That is, at least, shown in the record books. The Portuguese forward has scored in 78 matches in La Liga, of which the Whites have won 75 (96%) and drawn only three (4%).
