Leilua's contracted to the Green Machine for 2020, but he's been given permission his explore his options with the club unable to fit him into the 2021 salary cap.

He's facing a battle to hold on to his spot at right centre after he was given extra leave to get married in Samoa late last year.

Plus the Raiders recruited former Melbourne Storm centre Curtis Scott, who has already formed a combination - both on and off the field - with Raiders winger Nick Cotric.

Wests are circling Leilua after missing out on landing Latrell Mitchell, who jumped ship from the Sydney Roosters to arch rivals South Sydney.

He met with Tigers coach Michael Maguire on Monday as they look to add some strike to their outside backs.

Leilua would certainly do that, having scored 89 tries in his 204 NRL games - not to mention the six in six games he's terrorised the Tigers during his time in lime green.

A switch to Wests would see him team up with his brother Luciano, who made the move to Concord from St George Illawarra during the off-season.

Luciano played 43 games for the Dragons over the past three seasons and he still had a year to run on his contract.

But he needed a change and has signed on with the Tigers for three years.

If Wests want to lure his brother away from a high-flying Canberra, they'll need to make it worth his while.

He's believed to be on about $600,000 with the Green Machine for 2020, although he's already been paid almost a quarter of that.

"He's happy there. He's fine to stay [with the Raiders]. There's no dramas whatsoever," Leilua's manager Paul Sutton said.

Leilua has been a mainstay on the Raiders right edge throughout Cotric's career.

They played together in Cotric's debut, with the latter seeing first hand how damaging Leilua can be.

"I love him around the club, he's a great player. Not many other people can do what he can do," Cotric said.

"He's a great player, outstanding, he's a freak.

"Off the field he's a good fella too so I wish him all the best wherever he goes."
