While with Real Madrid, Ronaldo has played as both a wide player and a central striker, with Ronaldo playing as a Striker alongside Gonzalo Higuain during his debut season. Both Jose Mourinho and Carlo Ancelotti however deployed Ronaldo as a left-winger.
Playing from the left since his Manchester United days, when he started to show the capacity to score on a regular basis, Ronaldo has always had the freedom to cut inside and rocket a shot in on his favoured right foot.
Ronaldo has played 135 of his club games as a right winger, but the majority of those were during his younger days at United when he shared attacking duties with Wayne Rooney, Ruud van Nistelrooy and Louis Saha.
Cristiano Ronaldo has been deployed as an inverted winger.
Lionel Messi is interchangeable as an attacking midfielder or forward and is one of the finest players to ever pull on a football shirt. Messi can be absolutely devastating when he's on his game.
The vast majority of Ronaldo's goals have come via his favoured right-foot. But, while he's predominantly right-footed, he's also more than capable of hitting the back of the net with his 'weaker' left-foot. In fact, Ronaldo has scored an impressive 109 goals at club level with his left-foot.
Nominally not a striker, and certainly no target man, Messi has been playing a variant of a centre-forward role and out-scored anyone else who has played there in La Liga before.
Cristiano Ronaldo is set to stay at Manchester United next season despite reports that the striker will leave the club. Ronaldo is said to be confident of United's next managerial choice and will now prepare to see out his contract at Old Trafford.
While Ronaldo currently has more goals overall, Messi has the edge in the scoring department, with a higher season average (39.5 to 35), having hit a high of 73 goals in 2011-12.
And the concept of a 'False 9' – a forward who takes up their post shallower to your typical front man in order to link up play and keep things going – was invented back in the '70s by a certain Johan Cruyff.
A false nine is a centre-forward who repeatedly moves towards the ball in deeper positions from a high starting position, often dropping to receive centrally. The main intention is to get on the ball away from the opposition centre-backs – and, in doing so, to draw players out of position and disrupt the defence.
Cristiano Ronaldo as a midfielder scored 84 goals and supplied 45 assists in 196 Premier League games for Manchester United during six seasons in England.
1. Lionel Messi. Arguably the world's greatest ever player, Lionel Messi is another left-footed wizard capable of weaving all kinds of magic with a left foot that has been likened to glue because of his ability to retain possession and control of the ball.
Cristiano Ronaldo had found himself compared to Lionel Messi in almost every way possible in order to determine the best player in the world. One area in which the Portuguese megastar has an advantage over his Argentinean counterpart is his ability to use both feet with equal ability.
Cristiano Ronaldo, the best striker in history.
