The 28-year-old, who has played 23 times for the national team and scored 15 goals in the process, will headline the Fijian side at the OFC Nations Cup later this month in Papua New Guinea.
The Wellington Phoenix striker insists playing for Fiji is a top priority for him.
“I’m always the first to put my hand up for national duties and I will be available at any time to play for my country,” he says.
Krishna is one of the top candidates to captain his side at the Nations Cup.
He is also one of three senior players who will be included in Fiji’s U-23 squad for the Rio Olympics.
The Labasa-born forward says he is excited by the challenge in Brazil.
“It’s going to be tough in Rio, but nothing is impossible.
“We will be playing against teams with more experience and exposure on the world stage,” he says.
“Most importantly we have to work together as a team because teamwork is the secret ingredient to tackle the odds at the Olympic Games.”
Krishna is also looking forward to linking up with his Wellington Phoenix teammates in New Zealand prior to the Rio Games.
“I have learned a lot during my engagement with Wellington and there is still more to be learned, the bottom line is that I am satisfied with where I am today,” he says.
Earlier this year, Krishna and the Phoenix have agreed on a new two year deal which will keep him at the New Zealand based A-League club until at least May 2018.
