West Indies find themselves on the verge of a rare series win as they prepare to face England in the fourth Twenty20 International at Kensington Oval on Saturday, but off-field distractions have threatened to overshadow the moment, with rumours of disharmony in the squad dominating headlines instead.The Kieron Pollard-led side lead the five-match series 2-1 after winning last Saturday’s opener by nine wickets, losing the second T20I by one run 24 hours later, but then rebounding to capture Wednesday’s game three by 20 runs.However, within touching distance of only their fourth T20I series success in 12 tours, West Indies have had the spotlight trained instead on social media reports of rifts inside the squad which have already forced rebuttals from head coach Phil Simmons and Cricket West Indies president, Ricky Skerritt.Voice notes making the rounds Thursday suggested a breakdown in the relationship between Pollard and rookie fast bowling all-rounder Odean Smith, who was curiously given only one over in the first game, none in the second game and then strangely dropped for the third. Pollard bowled in those games.
