#2 LaLiga 2010-11: Real Madrid 6-1 Racing Santander
In the early days of the 2010-11 LaLiga season, Real Madrid needed to respond against Racing Santander to keep pace with league leaders Barcelona.
After Gonzalo Higuain provided the early lead to the home side, there was no looking back for Madrid. Ronaldo grabbed a quickfire double to all but end the game as a contest.
The former Manchester United man completed his first hat-trick of the season two minutes into the second period. And just before the hour mark, he converted a penalty to complete his first quadruple in European league football.
The Portugal international could have grabbed a fifth in the dying moments of the game but it was not to be. The Madrid giants eventually closed out a facile 6-1 home win.
