A versatile attacker , Ronaldo is capable of playing on either wing as well as through the centre of the pitch,  and, while ostensibly right-footed, is very strong with both feet.
While at Sporting and during his first season at Manchester United, he was typically deployed as a traditional winger on the right side of midfield, where he regularly looked to deliver crosses into the penalty area.
In this position, he was able to use his pace and acceleration, agility, and technical skills to take on opponents in one-on-one situations.
As Ronaldo matured, he underwent a major physical transformation, developing a muscular body type that allows him to retain possession of the ball, and strong legs that make up for an outstanding jumping ability.
These attributes allow him to function as a target-man, and makes him an aerial goal threat in the penalty area; consequently, many of his goals have been headers.
He also increasingly played a creative role for his team, often dropping deep to pick up the ball, participate in the build-up of plays, and create chances for his teammates, courtesy of his good vision and passing ability.
In his final seasons at United, Ronaldo played an even more attacking and central role, functioning both as a striker and as a supporting forward , or even as an attacking midfielder on occasion.

During his career, Ronaldo has also been described as having an "arrogant image" on the pitch,  with Ronaldo stating that he had become a "victim", because of how he was portrayed in the media.
Ronaldo has adopted several goalscoring celebrations throughout his career, including one particular celebration which gained widespread coverage in the media, when he squatted and stared directly into a camera on the sidelines of the pitch with his hand on his chin.
Both players have scored in at least two UEFA Champions League finals and have regularly broken the goal barrier in a single season.
Sports journalists and pundits regularly argue the individual merits of both players in an attempt to argue who they believe is the best player in modern football.
Some commentators choose to analyse the differing physiques and playing styles of the two,  while part of the debate revolves around the contrasting personalities of the two players: Ronaldo is sometimes depicted as an arrogant and theatrical showoff, while Messi is portrayed as a shy, humble character.
I think they have their own personal pride in terms of wanting to be the best". In a debate at Oxford Union in October , when asked whether FIFA president Sepp Blatter preferred Messi or Ronaldo, Blatter paid tribute to the work ethic of the Argentine before taking a swipe at Ronaldo, claiming "one of them has more expenses for the hairdresser than the other".
