The Portugal international is Madrid’s leading goalscorer on 450, having also struck 118 for Manchester United and five in his early days at Sporting CP.
Of his 600 goals, 102 have come from the penalty spot and 46 from direct free-kicks, out of a total of 87 from outside the box.
Ronaldo has 311 goals in LaLiga, 84 in the Premier League, 20 in Serie A and three in Portugal’s Primeira Liga.
