Paris Saint-Germain face a huge task to reach the Champions League quarter-finals after Cristiano Ronaldo defied predictions that his powers are waning with two goals as Real Madrid won 3-1 in the first leg of their Last-16 tie. Billed as a contest between World Player of the Year Ronaldo and his Brazilian heir-in-waiting Neymar, the 33-year-old Portuguese came out emphatically on top as he became the first player to score 100 Champions League goals for the same club.
