Billy Slater will need to know whether he can give 100 per cent before committing to play on in 2018.
Storm said last week they are hoping Slater would hold off on retirement and choose play on for at least one more season.
Speaking after the weekend’s NRL Double Header, the 33-year-old revealed he was still some time away from coming to a final decision.
“I have to make my mind up on what I want to do,” Slater told The Courier Mail.
“That’s just around whether I think I can put 100 per cent of myself into next year. I don’t want to commit and go in at 80 per cent. I don’t want to do that to the club.
“I need a couple of months to really work out myself whether I want to play next year.
“I’m feeling really good at the moment so I am looking at playing ... I just need a little bit more time.”
Slater has shown he is back to his best in recent weeks, producing three tries, three try assists and three line breaks in his last two games.
