Ballon D’Or winner, the Real Madrid forward is the most popular footballer in the world on Twitter with a cool 32 million followers. Cristiano Ronaldo is the greatest football player on planet earth. When all is said and done, he could even be considered the greatest player ever, at least at a club level. Granted, there will always be the spectre of Messi. However, while Messi seemingly declines with age, Ronaldo is doing the opposite. The older he gets, the better he gets. The goals and assists at Real Madrid are already in the double figures just a couple of months into the 2014/15 season.
