The AFL is facing a potential finals fixture headache with a storm brewing between the Swans and Giants over where an all-Sydney final should be played.

Sydney have called for the game to be played at the SCG irrespective of who earns hosting rights as the venue has a larger capacity than Spotless Stadium. The Giants, however, are adamant if they earn a final it should be played at their home ground, unless ANZ Stadium is available.

The Swans are also content for a derby final to be played there, however there are doubts whether the venue would be ready in time having not hosted an AFL match in two years.

It's believed the AFL has not ruled out using ANZ Stadium, which hosted the historic Swans-Giants qualifying final in 2016, but sources have indicated it is highly unlikely.
