Radradra is regarded as one of the world’s best rugby players having produced a series of standout performances for both club and country.

The 28-year-old back captained Fiji in the Autumn Nations Cup and has previously represented his country in sevens.

Baber is now looking to add Radradra to his squad for Tokyo 2020 and plans to speak to Bristol boss Pat Lam in a bid to secure his services.

The Gallagher Premiership season is due to end on June 26 - a month before the postponed Olympics is scheduled to start.

Fiji, eyeing a second successive Olympic gold medal at Tokyo 2020, are planning to train with Australia, New Zealand and Samoa before setting off to the Japanese capital and Baber hopes Radradra will be released from Bears to enable him to take part in preparations.

"Semi definitely has an intention and a desire to play in the Olympics and there will be conversations with Semi and Pat," Baber told Rugby Pass.

"The release of a player of that ilk is a big ask, and there are also players in the Top 14 like Vilimoni Botitu and Aminiasi Tuimaba at Castres and Pau, respectively. 

"They are high on my list having just dropped out of sevens to 15s."

Fiji made history at Rio 2016 when they won their first Olympic medal of any colour by clinching gold in the men's rugby sevens.

Playing under the leadership of Ben Ryan, the Fijian team thrashed Britain 43-7 as sevens made its Olympic debut.

Baber, who was appointed head coach in October 2016, is looking to repeat that success and expects his side to be boosted by the addition of Jerry Tuwau, who was recently named the World Rugby Men’s Sevens Player of the Decade.

"Jerry will do the Olympics," said Baber.

"He feels a responsibility and wants to push himself to win a second gold medal.

"That is his vision.

"We are working and developing players in Fiji and the issue the new guys have is that they have not played any international rugby sevens while players in Europe have that experience of walking into the cauldron of an Olympics.

"I have been in contact with Semi Kunatani and he had issues with Castres having been dropped for medical reasons.

"I have spoken to him about if things don’t work out in France then we would look at him being part of the training group.

"He is a great player.

"It’s a challenge for the boys in Europe to come down and join the squad in Fiji.

"We have regular contact with those players we have targeted and there is still an intention of a handful of them being part of the training squad.

"I had agreements with some of the clubs to get players released for up to four tournaments last season but that is not going to happen.

"It’s now about coming to Fiji and what impact the quarantine periods are going to have each time they come which is an added difficulty."
