#3 Ruud van Nistelrooy - 30 goals

Champions League greats Cristiano Ronaldo and Ruud van Nistelrooy have a lot of similarities. Both lethal goal scorers have moved from Manchester United to Real Madrid and are considered among the best players of their respective generations.
Van Nistelrooy, unlike Cristiano Ronaldo, started as an outright center forward. The two even shared a dressing room at Manchester United, and it can perhaps be said that Cristiano Ronaldo learned a few tricks from the Dutch goal-scoring machine.
Nistelrooy was well-known for his predatory instincts and goal-scoring abilities in front of the goal. The Dutchman scored 30 goals in just 35 Champions League appearances but sadly never won the Champions League.
#2 Alessandro Del Piero - 31 goals

Italian legend Alessandro Del Piero was highly different in his playing style compared to Cristiano Ronaldo but still effective. Del Piero had an extremely industrious nature on the pitch as he was more than a goal-scoring option.
He would often drop deep to create goals for his team-mates and had a natural creative side to his game simultaneously.
Unlike Van Nistelrooy, Del Piero managed to win the Champions League in his playing days. Before Cristiano Ronaldo's debut, he was the second-highest scorer with 31 Champions League goals in 61 appearances.
#1 Raul - 43 goals

At the top position sits Raul, whose baton was naturally passed to Cristiano Ronaldo himself eventually.
The Spaniard was a prolific goal-scorer who was well known for his scoring abilities and consistency. Like Cristiano Ronaldo, Raul was a dependable figure in front of the goal, and he used to deliver the goods more often than not.
But he was also equally creative on the pitch. He had the trait of dropping deeper and building the play alongside him, which made him one of the most complete strikers.
Raul scored 43 Champions League goals in 79 matches, and just like Cristiano Ronaldo, he won the Champions League multiple times with Real Madrid.
