Perhaps the greatest all-rounder to have ever graced the game in the past twenty years, Jacques Kallis makes our list at No.4.

The only cricketer to score over 10,000 runs and accumulate over 250 wickets in both ODI and Test cricket, Kallis remains a modern-day colossus.

With a pristine technique against both pace and spin and a bag of tricks as a bowler, Kallis, who made his debut for the Proteas in 1995, went on to become the cornerstone to their success in his nearly two-decade-long career.

In a career that went on till 2014, Kallis represented South Africa in 519 matches across formats, accumulating 25,534 runs at a cumulative average of 49.10.
