Mahendra Singh Dhoni- India's most successful cricket captain- finally bids adieu to international cricket. Also known as captain cool, he changed the face of Indian cricket by winning the inaugural World T20 trophy in Johannesburg in 2007. Later in 2011, Dhoni won India the cricket World Cup final against Sri Lanka at Mumbai's Wankhede stadium. He is the only cricketer to win all three ICC Trophies (ODI World Cup, T20I World Cup and Champions Trophy). Dhoni, who started out as a railway ticket collector, ended his career as one of the game's greats.
