Sri Lanka captain Mahela Jayawardene is confident his side can carry their excellent form to South Africa and win the inaugural ICC World Twenty20.
Jayawardene expects Sri Lankan success at the Twenty20 World Cup
"Our bowling attack is very good and so is the batting as it consists of proven performers," he said.
"Our intention is to challenge ourselves and we feel we are capable of winning the championship."
Sri Lanka start off against Kenya and then face a tough game with New Zealand in Johannesburg on 14 September.
But both sides are expected to progress to the Super Eights stage from a group which also includes Kenya.
Sri Lanka side are relatively inexperienced in the 20-over format of the game having only played three Twenty20 internationals, the most recent of which was in December, when they lost to New Zealand by five wickets in Auckland.
But they have stuck largely to the squad which reached the final of the 50-over World Cup in April before losing to Australia and Jayawardene said: "I believe we should play the way we are used to and adopt our brand of cricket which has served us well up to now.
"I think it is all about keeping a cool head as one cannot make too many mistakes and expect to come back as it is a very short game...the key will be to minimise mistakes as we do in other games.
"We will attempt to take a game at a time which is the best way to move forward."
