Sydney FC has sealed the domestic triple crown with a 2 – 1 win over Adelaide in the FFA Cup final.

The Sky Blues did it the hard way, with Brazilian striker Bobo scoring the winning goal in the second period of extra-time.

Frustrations boiled over in the final minutes with Adelaide player Michael Marrone sent off for crashing into a ball boy.

2GB’s Alan Jones spoke to winning coach Graham Arnold.

” I couldn’t be prouder of the boys after last night.”

With three games in eight days, Graham told Jones they’re taking it one game at a time.

“It’s a short turnaround of only two days between games which is really tough.”

The competition started out with over 700 teams.

” I think it’s a great concept from FFA to bring this competition in. It gives the opportunity to a lot of clubs … to play at the top level.”

But Arnold believes the final needs to be on a stand alone weekend, rather than mid-week.

“I think it deserves a little bit more respect. Tuesday night, 7:30 kick off. It’s tough for the families to get out and watch the game.”
