Allegations of poor behaviour by West Indies players during their recent tour to Australia could cost the team a $20m sponsorship agreement. Caribbean cricket journalist Tony Cozier told the BBC there was a "real danger" Digicel could scrap the deal. The claims came in a leaked memo from Richard Nowell, who travelled with the team on Digicel's behalf. "They are the poorest ambassadors from any representative team I've come across," Nowell commented. The West Indies Cricket Board will meet in Barbados on Sunday to discuss the contents of the memo. They will also consider reports from team manager Tony Howard and coach Bennett King. The five-year deal with Digicel is the biggest in West Indies cricket history. "It is my understanding that Digicel's chairman Denis O'Brien, Nowell himself and the CEO of the West Indies Cricket Board Roger Brathwaite did have a meeting in London last weekend. "Digicel spelt out their frustration....that the sponsorship was getting them nowhere, quite the opposite in fact it's having a negative effect," Cozier told BBC Caribbean Radio. "I think the West Indies Board has to be very concerned over whether it will lose the Digicel sponsorship. "A loss of $5m is forecast for the current financial year, compared to a profit of $3m in the previous financial year." In the memo, Nowell accuses players, many of whom, like captain Brian Lara, have personal sponsorship deals with Cable and Wireless, of being uncooperative and lethargic. Allegations WICB spokesman Leonard Robertson told the BBC: "The first allegations surfaced in a Trinidad newspaper on Thursday. "The contents of that memo certainly involved statements that affected the West Indies players. "The article was passed on to the coach and manager. We expect to have some comment about the whole issue in due course." But Dinanath Ramnarine, president of the West Indies Players Association, hit out at the allegations and said the team had "fulfilled all their contractual obligations" with the company. The leaked memo, which later appeared in full on the Caribbean Cricket website, follows a pre-tour dispute between the Board and the players following the announcement of the Digicel deal. It was eventually resolved after a judge was appointed to arbitrate between the two sides. West Indies won only one of their six VB series matches in Australia and failed to qualify for the final, a marked contrast to their performance in winning the ICC Champions Trophy in England last September. Robertson said Sunday's meeting was a scheduled post-tour de-brief. But he added: "The issues surrounding that report will also be discussed." A Digicel spokeswoman contacted by BBC Sport declined to comment. Reprinted from bbccaribbean.com
