In 2014, the late, great former New Zealand captain Martin Crowe proved prophetic when he proclaimed Joe Root, Virat Kohli, Steve Smith and Kane Williamson to be "Test cricket's young Fab Four" in a column for ESPNcricinfo .
At the time, Root was the only one who averaged above 41 in Test matches and none of them had been ranked as the best batter in the world. "All four have similar talent, hunger, ambition and responsibility," Crowe wrote.
"All four will go on to captain their countries. All four will reach peak form in a few years' time, and then the real battle will commence as to who will be the No. 1 batsman in the world. My sense is that they will all take turns as the No. 1 Test batsman."
