England skipper on Thursday won the toss and elected to bat first against West Indies in a Group B match at MA Chidambaram Stadium in Chennai. England head into this match knowing defeat will send them crashing out of the World Cup. England have made three changes in their team that lost to Bangladesh. Chris Tremlett comes in for out of form James Anderson , Luke Wright replaces Paul Collingwood and James Tredwell comes in for Ajmal Shahzad. Even victory may not be enough for Andrew Strauss's men to go through to the knockout stages, with England having to rely on other results going their way. On the other hand the West Indies, led by Darren Sammy, have a slight edge having won all their last three games after the loss to South Africa, but they have not yet been fully tested in the ties having played against lowly-ranked opponents. Teams: England: AJ Strauss(c), M Prior, I Trott, I Bell, E Morgan, R Bopara, L Wright, T Bresnan, G Swann, J Tredwell, C Tremlett. West Indies: D Sammy(C),C Gayle, D Smith, D Bravo, R Sarwan, K Pollard, D Thomas, A Russell, S Benn, D Bishoo, K Roach.
