Adelaide fans have plenty to sing about

Winners are grinners and 40,000 Adelaide United fans were smiling, singing, cheering and dancing as they streamed from Adelaide Oval on Sunday, 3-1 winners over Western Sydney Wanderers in the A-League grand final.

After almost lifting the roof of the stadium at the final whistle, the Red Army were still celebrating as they made their way from the ground, unlikely champions considering their team's winless start to the season.

"We started from the bottom and now we're here, champions," one Adelaide fan said.

In contrast the normally vocal Wanderers' fans were quiet as they filed out but took their defeat in good spirit, some suggesting Adelaide was the better side on the day.

Despite being just 10,000 strong, they had made their voices heard during the game, especially during the second half when the Wanderers closed to within a goal after trailing 2-0 at half-time.

But the third Adelaide goal on the verge of extra time put the result beyond doubt and left them with little to cheer about.
