Another common criticism of Ronaldo, though probably not as common as the previous criticism in this slideshow, is that he melts under pressure, and is simply not good enough when the big games come around.
Ronaldo haters and skeptics have certainly been provided with a decent amount of ammunition for this criticism.
Immediate examples of Ronaldo choking under pressure that come to mind are his missed penalty in the 2007-08 Champions League final against Chelsea, as well as his poor performance in the 2008-09 Champions League final against Barcelona.
Ronaldo's performances internationally for Portugal have also provided skeptics with a great of ammunition, as Ronaldo was unable to will his team to victory against the technically inferior Greece in Euro 2004, and was also rather ineffective in Portugal's unsuccessful 2010 World Cup campaign.
Yet, as with his passing, this is a flaw in Ronaldo's game which he has improved on significantly in recent years.
For Real Madrid, Cristiano Ronaldo has performed well in multiple big games. He scored the penalty in the second Clasico match of the 2010-11 season, and scored the winning goal in the following Clasico match, which was the Copa del Rey final.
As for Portugal, the argument for Ronaldo being a poor performer internationally has generally been a weak one.
Ronaldo was a dead-on candidate for Best Young Player of the 2006 World Cup before his conduct in the Portugal v England match resulted in the award being given to Podolski, and Ronaldo goalscoring record of 32 goals in 87 international caps is definitely nothing to scoff at.
But much more recently, Ronaldo proved against Bosnia & Herzegovina that he can be his country's hero when the pressure is on.
With Portugal needing to win at home to get to Euro 2012, it was Cristiano Ronaldo who scored two sublime goals to kickstart Portugal's 6-2 rout of B&H and secure Portugal's place in the competition.
Long story short: Ronaldo has had trouble shining in the big games where his skill and magic is needed, but in recent years he has definitely shown much more poise than he has in the past.
If he continues to improve at this, he undoubtedly become a much more dangerous player than he already is.
