New Zealand eye Bangladesh win to complete World T20 whitewash

New Zealand will be looking to maintain their perfect record at the World Twenty20 on Saturday when they face a Bangladesh side that already know they are going home.

The Black Caps are already assured of a place in next week's semi-finals after defeating India, Australia and Pakistan in their group so far.

New Zealand are yet to win any of cricket's premier short-form competitions, and captain Kane Williamson will be looking for his side to keep the momentum going into the business-end of the tournament.

Their approach has been to rely on spin, with Trent Boult and Tim Southee, the team's main strike bowlers in one-day internationals and Tests, staying on the bench.

Martin Guptill scored 80 during Tuesday's victory over Pakistan, and he has revealed New Zealand may not keep the same line-up, but insists there is no reason why they cannot get out of the group with a 100 per cent record.

"We've got a mind-set of being aggressive and just going out to have a bit of fun," he said.

"At the moment, everyone is having fun playing cricket, and we are playing some good cricket together, putting in some good performances.

"If we can do that again against Bangladesh, who knows, we can go through unbeaten."

The match represents Bangladesh's last chance at returning home with something after three straight defeats, including a heart-breaking last-ball loss to India on Wednesday.

After his team took India right to the wire, Bangladesh captain Mashrafe Mortaza knows his players must put the experience behind them.

"It's always difficult to take something from it [a close defeat] to another match," he said after the India game.

"But obviously being professional players we have to take it and play hard cricket in the last match. Obviously if we can do something there then we can take something back home."
