The Uruguayan, whose English has improved in the past 18 months, took the unusual step of reading his acceptance speech off palm cards.

Fornaroli thanked the club’s owners, sponsors, coaches, support staff, players and fans before signing off by dropping the expletive.

The City striker also won the Mark Viduka medal for best afield in the cup final as City triumphed 1-0 over Sydney FC.

Fornaroli was later asked about the expletive and admitted it was a regrettable moment, showing some remorse.

"This moment I'm very tired but I say sorry for what I say,” Fornaroli said.

It's not the first time a bizarre incident has occurred during an FFA post-final ceremony, with former chairman Frank Lowy tumbling off the stage after the 2015/16 A-League Grand Final at the same venue.
