PORT Adelaide coach Mark Williams says he would be ‘amazed’ to still be at Alberton beyond the end of next season, adding that he would need to win a premiership to earn a new contract with the club.

This time last year the long-serving coach was re-signed for a further two seasons following a highly publicised and drawn-out process.

Williams surrounded himself with new faces, including assistant coach Dean Laidley and former Geelong star and development coach Garry Hocking and the Power appeared invigorated as a result, winning five of their first seven games this season.

Port Adelaide has since slumped to 12th on the AFL ladder and on the verge of missing the finals for the third straight year, prompting calls from former West Coast and Hawthorn coach Ken Judge for Williams to walk away from the club.

Williams said he saw no reason to leave the club now, but conceded that it was unlikely he would remain in the top job after his current contract expires at the end of 2011.

“I would be amazed if I was there more than two years, this year and next,” he said on Friday.

“If you are interested in protecting your win-loss record … that is the only reason you would [leave now]. I see great development in our group. I see a group that has been fractured by injury, but there is a willingness to improve and to work hard and when we get the group back together we will be a very viable side.”

Williams has been involved with Port Adelaide since before it joined the AFL in 1997.

He took the Power to their first and only premiership in 2004 and to an unexpected grand final in 2007.

The club is on the verge of a record seven-game losing streak and Williams said he understood why people were questioning his position at Alberton.

“We have lost some games and I've been there a long time ... all those things are factored in, but if you want to spend some time to come and see what we do [you’ll see that] we work hard and that the players enjoy the environment,” he said.

“To be in the predicament we are in, the feel around the group says something about the management and how it all works. It is great to get the support of the players, the other coaches and the administration. From where we are at the moment it is a good as it could be.”

There has been speculation Williams could be lured to join former mentor Kevin Sheedy at Greater Western Sydney next year.

Williams responded to questions about a potential move by saying “I’m in contract” and denied his coaching methods had become stale with the players.

“People who know me well know that I am innovative. I get bored myself and I actually try different things myself. Dean and Garry Hocking coming in was good and Jenny [Williams] and Jan Stirling was good … bringing new people in is always exciting.”
