​Cristiano Ronaldo and Lionel Messi are arguably two of the greatest footballers in the history of the sport, but there is no doubt that they are the best in UEFA Champions League history. 

Ronaldo opened his account for new club ​Juventus ironically when he scored against former employers ​Manchester United in their encounter on Wednesday to take his tally to 121 in the competition.

Messi on the other hand has 105 goals to his name, though took lesser time to reach the mark as compared to his great rival. The Argentinian needed only 123 games to reach the century mark while Ronaldo took 144 games to bring up his 100 goals.
