Ken Sio is hoping some impressive performances for the Newcastle Knights will help win them over to give the winger a new contract extension.

The 27-year-old is the Knights' leading try scorer with 10 tries for the season, which includes a terrific acrobatic try in the win over the Panthers last weekend.

Sio has played 18 games for the Knights in 2018, making 12 line breaks and racking up a total of 2041 running metres.

The winger has publicly stated he wishes to remain in Newcastle and while negotiations are underway, the Knights have been non-committal for the moment.

Newcastle signing winger Edrick Lee from Cronulla on a three-year deal has put some doubt over the playing future for Sio at the Knights and he is hoping some solid performances will be enough to secure him a new deal.

Sio said he'll just have to wait and see what happens at the end of the season.

“It would be awesome to stay, but it’s with my manager and I’m sure we’ll get an update sooner or later,” Sio told the Newcastle Herald.

The signing of Lee will be a giant boost for the Knights, with Sio believing he'll be a great player for the club and will help out with their depth.

Competition between teammates is always healthy, with Sio and back-rower Lachlan Fitzgibbon aiming to be the Knights highest try scorer for 2018.

Sio explained he is stoked to have contributed with 10 tries this season.

“I hardly got any tries [five] last year, so it’s been a good year for me,” he said.

“Fitzy is also right up there and there’s still two more games after this, so you never know how it will go.

“I’ll just be trying to finish off all the opportunities the boys present for me.”

When it comes to Sio's incredible put down in the Panthers clash, he stated half was practice and half was instinct.

“You’re looking to finish it off and stay in, but then also you can’t see the sideline as well,” he said.

“There’s some spectacular finishers in the game now, who know when to jump.

“It’s just a matter of timing it.”

If Sio is to earn a new contract with the Knights, it will see him enter a seventh season in the NRL.
