Cristiano Ronaldo: 5 times the Portuguese proved he is the king of the Champions League

#2 Scoring 17 goals in a single season

Ronaldo scored a record 17 goals in the 2013/14 Champions League

During the 2013/14 campaign, Real Madrid managed to break their 12-year wait to win the Champions League and finally complete 'La Decima'.

It was an incredible season for Los Blancos that will remain in the memory of those who watched it, especially with regards to Ronaldo.

Up until then, Lionel Messi's haul of 14 goals was the record total in a single Champions League season, and although Ronaldo had been close to that figure, he had never equalled or surpassed it.

All of this would change in 2014 when Ronaldo scored two goals past Bayern Munich in a semi-final away tie to take his total to 16 goals for that season.

However, Ronaldo wasn't finished as he topped off his perfect Champions League campaign by scoring in the final against Atletico Madrid deep into extra time to complete a 4-1 victory over Los Blancos' city rivals.

Ronaldo's goal-scoring ability is his greatest trait, and this achievement shows it. No other player has managed to cross the 15-goal mark in a single Champions League season apart from Ronaldo, who has done it on three occasions.
