Sir Vivian Richards: Two-time World Cup winner Sir Vivian Richards has urged unbeaten India to stay positive and attack at all costs as they attempt to win a third title at this year's event.

India have taken all before them at the 13th edition of the World Cup this year and have won all eight matches they have appeared in to sew up a spot in the semi-finals next week.

Richards - renowned as one of the most flamboyant and attacking players of his time as he helped the West Indies to World Cup success in 1975 and 1979 - wants to see India continue to play to their strengths and avoid any negative thoughts as they strive to stay unbeaten and add to their previous titles in 1983 and 2011.
