Krishna, who will rejoin his Waitakere club in September, was not initially named in the side but later recalled to boost the nationals team's chances in this year's championship.
"There isn't much difference between 11-a-side soccer and Futsal. We need more speed and have to possess good skills to be a good Futsal player."
The national side has never won the OFC Futsal Championship and Krishna is hopeful of our chances this year.
"All players competing will want to win this championship. We got a good squad and we will do our best to win this year."
Team manager Krishneel Sharma said Krishna's inclusion had boosted the morale of the national side.
"We are glad about Roy's inclusion in the side. His presence will be a big boost to the national side in the upcoming championship."
Meanwhile, the national side marched into camp on Monday and Sharma was pleased with turn up of the players. "The players will be having two training sessions per day from Monday to Friday. They will be released for the weekends."
"Once we will trim the team to 15 members, then we will go into two weeks of training directly leading to the championship in August."
Sharma also confirmed the players will be given release to play for their respective district side in the National Football League competition.
