Sri Lanka captain Dasun Shanaka is confident about his team putting up an impressive show ahead of the all-important T20 World Cup set to be played in Australia this month.

Just recently, Sri Lanka were bolstered by a win in Asia Cup, where they defeated India once and Pakistan twice in consecutive matches in the United Arab Emirates. The turnaround in that competition was an impressive one as they were hammered by Afghanistan in the opening game.

Ahead of team's departure to Australia, the confidence brimming from Shanaka's side is much higher. "If we make the right decisions on the day and execute our plans, I'm certain we can come out victorious," he said [as quoted by Cricinfo].

"The confidence level is definitely higher [than at the last World Cup], but my concern has always been the process. Even at the last World Cup, I felt we had the talent to at least make the semi-finals. The important thing is your ability to play and deliver on the day."

Sri Lanka will face Namibia in the first-round game of the World Cup on October 16 and are heading to Australia almost two weeks prior to the start of tournament. Sri Lanka went under a training camp in Kandy before their departure, where they have been very specific in terms of what exactly they need to work on as a unit.

"With the bowling we're still working on yorkers, to make sure we can be successful on Australian wickets, to make sure we have the skills to back our plans up," he said.

"We have a couple of warm-up games before the Namibia game. We'll play match scenarios amongst ourselves before that to make sure we can control the environment that we're training in.

"We're actually very specific about what we're trying to train. For example, we did a Super Over up in Kandy, which is all in good fun, but it highlights where it can be a bit chaotic in the Super Over. It happens very quickly, and we have to make sure we keep a level head."

The other thing which sides will be working on is getting used to the big grounds in Australia and as to how the fielders will have to position themselves to cut the angles down.

"Then the dimensions of the grounds in Australia - they have some big grounds - we'll have to learn to cope with them. We have to make sure we get the distance right off the boundary to cut the angles down and get the guys used to doing that."
