See the cheeky social media post that fuelled a feud between the Sydney Swans and GWS Giants

The rivalry between Sydney and GWS has grown to be one of the fiercest in the game - but a recent post from the Giants' social media team has taken things up a notch.

The two Sydney clubs have never been on the best of terms, but the launch of the Sir Doug Nicholls Round this week illustrated just how bad things have become between the teams.

The AFL planned for all the clubs to come together for a photo shoot to celebrate the Indigenous round. 

The Victorian teams got together in Melbourne and South Australia's sides joined forces in Adelaide - but when GWS asked the Swans when they should meet, they were reportedly given the cold shoulder.

A recent post by the cheeky GWS social media team that was published just before the two teams clashed in the Battle of the Bridge a few weeks ago is responsible, according to the Herald Sun.

The Swans were not happy with their video making fun of coach John Longmire pronouncing the name of Giants midfielder Stephen Coniglio incorrectly - saying 'Con-ig-lio' instead of 'Con-eel-io'. 

Other posts from GWS referencing rumours that Sam Wicks was offside with teammates due to a dispute over a woman were also not appreciated by the Swans.

According to Swans great Paul Roos, the club is very much against a public war of words.

'I think that goes way back,' he told the ABC's AFL Daily podcast.

'I can only talk to when I started as a [Swans] player under [coach] Rodney Eade … we were trying to fit into a rugby league and rugby union town, and we were always really respectful of where we sat, respectful of the other codes.

'I think that's just a spill-over from that generation that taught us that we were going to be really respectful of everyone and we were going to be really competitive.

'When I was coaching we didn't generally buy into any of the garbage that was spoken, and John Longmire is the same now.

'The game is played on the field and that's where the rivalry has really lifted, to be honest.

'I don't care what's said off the field, but you've got to be able to back it up.

'The rivalry has grown because both teams are now really, really good teams, and that's what I'm excited about.'
