Worsfold, entering his eighth year in charge of the club, is one of four premiership coaches out of contract at the end of this season, and one of seven coaches in total.
But the Eagles mentor said he would be coaching again in 2010 if he achieved the goals he set for himself and the club.
"[I've got] no doubt that I’ll get signed -- not the other way," he said on Tuesday.
"Of course there are [things I have to achieve] but I've got no doubt I'll achieve those.
"I've got a fair idea of how much I'd like to improve. I may have set my sights higher than what our board expect. I'm aiming to achieve the goals I've set and if I do that I've got no doubt I'll still be coaching this club next year."
Worsfold said with his contract running until the end of this season, speculation about his job would only be a distraction if losing his post mid-season became a possibility.
He said after seven seasons in charge, including six finals series and the 2006 premiership, he already considers himself a career coach.
"I haven't set a 20-year goal. I've set a goal to enjoy coaching," he said. "So I would probably say that after eight years it's been a career.
"Whether you want me to become a grumpy old veteran coach, I've probably got to hang in there for another eight years.
"I really enjoy it and while I'm really enjoying it, and while I'm doing a job that supporters, players and the football club believe is good enough, then I'll keep doing it."
With the side's round one clash with Brisbane four days away, Worsfold said his squad was in the best possible shape. He said the climb back from a 15th-placed finish in 2008 was the start of a new era the club and an exciting time for everyone involved in West Coast.
"There's different things happening. We've got new players coming through [and], young players that are stepping up into a more mature bracket. That's exciting. It's an exciting place to be around. Payers have done a lot of work and I'm looking forward to seeing them strut their stuff."
