Marlon Samuels      

Marlon Samuels is a right-hander of immense ability, but he hasn't come close to realising his potential, thanks to the various controversies he has been embroiled in. When he started his Test career at 19, without yet representing his native Jamaica in a first-class match, his composure and skill prompted comparisons - quite unfairly - with Viv Richards. His technique was near to faultless, and he exudes a bull-headed confidence - he used to skip his schoolwork on the basis that exams were irrelevant to future Test cricketers.

However, that confidence, which often overflowed into perceived arrogance, has landed him in plenty of trouble. It almost got him sent home from India late in 2002 after he defied a team curfew - but he was kept on, and responded with his a disciplined maiden Test century in Kolkata. His lack of consistency meant he remained an irregular member of the team in the 2000s, but just before his selection for the 2007 World Cup, he was drawn into a major controversy after Nagpur police alleged that he passed on match-related information to an alleged bookie ahead of an ODI against India. He was included in the World Cup squad despite the ICC's investigations into the issue, where he only briefly shone, ending the tournament by running out Brian Lara in his last international innings.

He was called for the World Twenty20 in South Africa in 2007, but the match-fixing allegations reared its head in 2008 when he was found guilty of "receiving money, or benefit or other reward that could bring him or the game of cricket into disrepute." Samuels was subsequently banned for two years, at a time when West Indies desperately needed solidity in their middle-order. He returned to the West Indies Test and ODI teams in 2011, hoping to find the consistency that had eluded him so far in his international career.
