WATCH: Player goes crazy celebrating goal - then sees it's been ruled offside

An uninformed observer would be forgiven for thinking they had just won the league.

Oh dear.

Sydney Wanderers striker Kerem Bulut thought he had given his side the lead against Melbourne City earlier today and it clearly meant a lot to him.

Bulut raced to celebrate with Wanderers fans, leaping an advertising hoarding in the process.

Supporters were equally keen to join in, embracing the their hero on the sidelines.

An uninformed observer would be forgiven for thinking they had just won the A-league.

Which made it all the more embarrassing when he eventually heard the whistle and realised he had been flagged for offside.

Morto for you Kerem.

The game ended in a 1-1 draw.
