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.

โ€œIt would be awesome to stay, but itโ€™s with my manager and Iโ€™m sure weโ€™ll get an update sooner or later,โ€ Sioย 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.

โ€œI hardly got any tries [five] last year, so itโ€™s been a good year for me,โ€ he said.

โ€œFitzy is also right up there and thereโ€™s still two more games after this, so you never know how it will go.

โ€œIโ€™ll just be trying to finish off all the opportunities the boys present for me.โ€

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

โ€œYouโ€™re looking to finish it off and stay in, but then also you canโ€™t see the sidelineย as well,โ€ he said.

โ€œThereโ€™s some spectacular finishers in the game now, who know when to jump.

โ€œItโ€™s just a matter of timing it.โ€

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