Kumar Sangakkara is confident Sri Lanka will transfer their fine Test form against New Zealand into the upcoming two T20I's.

The hosts secured a 2-0 whitewash in the recent Test series against the Black Caps and Sangakkara is convinced the hosts have to quality to also triumph in the shorter form of the game.

"The batting of Tillakaratne Dilshan and Mahela Jayawardene was extraordinary in the Tests and everyone else played their part," said Sangakkara.

"Everyone chipped and it just goes to show that if everyone is willing to fight, show character and put in the hard work as a team, results will follow.

"I'm sure with those qualities in the side we can walk away with a win."

With the form shown by Dilshan and Jayawardene and with several talented youngsters pressing for inclusion, Sangakkara admitted selecting the final line-up would be difficult.

"Every game we go into we are looking to win and to give it our best," he said.

"We've got to think long and hard about our combination for tomorrow's game.

"One good thing over the last two years with coach Chandika Hathurusinghe doing some great work with the A side is that we have a lot of young players coming through with top quality.

"So the talent is there and if we do our homework right, be confident, prepare as best as we can and go out there looking to win, and if our attitude is positive, we will do well."

Former skipper Jayawardene, who relinquished the captaincy so that Sangakkara could build a side for the 2011 World Cup, is happy with the progress of the team.

"Sangakkara is a very good leader and the team is heading in the right direction," Jayawardene said.

"As long as we keep motivating ourselves to be better cricketers we can keep challenging ourselves to be a better team in all forms of the game."

Sri Lanka have included uncapped 23-year-old all-rounder Gihan Rupasinghe in their squad along with fast bowler Isuru Udana, who featured in the World Twenty20 in England, and Mahela Udawatte.

Angelo Mathews' recovery from a hamstring injury gives Sri Lanka a happy problem of plenty.

The core of the New Zealand team remains from the Test series, although the Black Caps do welcome the arrival of fast bowlers Kyle Mills, Shane Bond and Ian Butler as well as Brendon Diamanti and Neil Broom.

"There's an air of confidence about the team when it comes to the shorter form of the game," captain Daniel Vettori told Radio Sport ahead of the Twenty20 matches tomorrow and Thursday.

"We've got a number of personnel changes, but the core group still stays the same and I think guys have a real confidence in their own ability in the one-day format.

"So I hope we see a turnaround in our performances. We need to win these games as we build up to the Champions Trophy. It's a short and sharp tournament and you need to hit it running."
