Reds triumph yet to sink in: Galekovic

Feted by thousands at a raucous public celebration, Adelaide United captain Eugene Galekovic still can't quite believe it.

"It's unreal. It's special," Galekovic told AAP on Monday as United's A-League grand final after-party continued.

"I think it will sink in in the next couple of days when we watch the game over and just see those special moments."

Galekovic and his triumphant United teammates were greeted by thousands of fans in the heart of Adelaide on Monday, a day after their 3-1 grand final win against Western Sydney.

The entire Adelaide playing squad and coaching staff, with championship medals around their necks, were presented on a makeshift stage at Rundle Mall.

"This is a beautiful feeling," coach Guillermo Amor said.

"To see the city like this, I am really enjoying the moment."

Galekovic carried the A-League championship trophy and striker Bruce Djite held the Premiers Plate, while teammate Craig Goodwin summed up the mood.

"Just joy," Goodwin said.

"Everyone is just ecstatic.

"It's immense. It's the first time we have won the A-League title and to take out the double as well has been amazing."
