Wicketkeeper-batsman Sanju Samson, who plays for Rajasthan Royals in IPL, has named Windies spinner Sunil Narine, who plays for Kolkata Knight Riders, as the toughest bowler he has faced. "Though I have played well against him, he's a superb bowler," said 25-year-old Samson who is yet to make his ODI and Test debut. Samson has played four T20Is for India.
