Canberra five-eighth Jack Wighton has had the best seat in the house watching the career-best form of NRL star Aidan Sezer in recent months.

Wighton said it will be “tough” for coach Ricky Stuart next year deciding between incumbent halfback Sezer and England international signing George Williams.

Sezer booted three field goals in the Raiders’ golden-point win against the Sharks last Sunday to all but clinch the Green Machine’s second top-four finish in 16 years.

Sezer has played every game since round 12, following an injury-plagued start to the campaign, and led Canberra to a 9-3 record in that stretch.

The 28-year-old will be fighting for his spot in 2020 when England halfback Williams arrives but Wighton said Sezer’s form speaks for itself.

“He’s been good and playing with a really level head. He’s controlling the team around the park and doing all the little things which has been a massive help,” Wighton said.

“He’s so dangerous and very quick. It takes a lot of pressure off me when he’s running (at the line) and opening up more space for me.

“He’s kicking, he’s running and he’s passing, so (opposition) have to be on their toes with him and you can see it with the way he’s playing, he’s pulling teams apart.

“It’s a tough one for the coaches (next year).”

Stuart has rested Charnze Nicoll-Klokstad, Jordan Rapana, Sia Soliola and John Bateman for their final-round clash against the Warriors on Sunday.

Wighton has played more minutes, when including representative football, than any of his club teammates this season but the NSW star refused to be rested this week.

“I’m feeling good now, I have to admit for a few weeks after the Origin series I was very flat but all that is gone now. I’m feeling excited, I can’t believe it’s almost finals time,” Wighton said.

“I just really want to play at the moment. It’s that time of year and as everyone says you don’t get many chances at it so I’m keen to keep ticking it off week by week and stay on the field.”
