Raina said the main World Cup will start for them tomorrow and they are the team to win the title. "We need to just go in there and play to what we have in the dressing room. We can't just think what we have. We have played a lot of matches against them.
"We just need to play positive cricket, need to do proper process in bowling, batting and fielding. I think we will do well and definitely the team to win the World Cup. So I think it's going to start. The main World Cup is going to start for us tomorrow," he added.
