Lauding the young Karnataka lad, Shastri said the 24-year-old batsman has left India's Test skipper Virat Kohli behind to emerge as most improved cricketer in the world and he will prove to be a big asset for Indian cricket.
"KL Rahul is the most improved player in the world in last one year. He is not only good in Test cricket, but in other two formats. He has a great future ahead of him," Shastri was quoted by TOI as saying.
Kohli's meteoric rise in every format of the game has already kept cricket enthusiasts in awe but young Rahul, who plays under Kohli in Royal Challengers Banglaore, emerged as another 'all season batsman'.
Rahul has a century in every format of the game on International platform, a feat even Kohli hasn't yet achieved, is only grabbing attention with every match.
Having already impressed experts with his calm and composed innings in Test cricket, the youngster is now making all the right noises in limited overs' format too.
The stylish right-handed batman has an added advantage of being a wicket-keeper which will give him an edge over others.
What makes Rahul even more special is the fact that he has a wide range of shots in his book. He can shift gears at will and his running between the wickets is also impressive.
