The A-League has broken all kinds of attendance and TV viewing records over the first fortnight of the season, thanks largely to the effect of marquee signings like Alessandro Del Piero and Emile Heskey.

Saturday night's first-ever Sydney derby is already a sell-out, continuing the feel-good start to the campaign.

While admitting the level of interest and the figures generated so far had come as a bit of a surprise, Buckley said there was no time to sit back and admire their work.

"It's been a fantastic few weeks there's no question about that," Buckley said. "We've had record crowds, record TV ratings and we've got some incredibly exciting contests coming up over the next few weeks.

"Our crowd average is up 55 percent, TV audiences are up in excess of 30 percent again so that augurs well.

"But we've still got a lot of hard work to do. We're only up to round two.

"The clubs have worked very hard with their supporter bases over the off-season and we need to continue to work hard to constantly improve."

Asked what the key was to continuing the unprecedented hype surrounding the league, Buckley said: "It's not just clubs, it's the FFA and the A-League management and clubs working in partnership together to grow our membership base.

"We need to engage effectively with the community to take advantage of the potential that exists.

"That's about getting the marketing right, getting the membership packages right and those things by and large are going well this year."
