Perth coach Ian Ferguson is eager to turn the Glory into an A-League powerhouse, but says he needs a multi-year contract extension in order to make it happen.

The Glory took another step towards securing a top-four berth with a crushing 4-0 victory over struggling Gold Coast at nib Stadium on Monday night.

The result extended Perth's unbeaten run to a club record eight games but more importantly created a four-point gap between the fourth-placed Glory and fifth-placed Heart.

Ferguson is out of contract at season's end but is almost certain to be offered a new deal barring a remarkable collapse in form.

However, the Scotsman wants more than just a one-year extension in order to ensure the progress made this season won't be lost.
