Reports have emerged that Socceroos star Tim Cahill could be the face of third Sydney based team.

The Sydney Morning Herald has reported that Cahill is eager to get involved with a possible new team in Southern Sydney, with the future of the Wellington Phoenix looking more and more shaky by the day.

It is believed that a team in the region would be ready to go should the Phoenix cease to exist in the A-League next season.

Sutherland Shire Mayor Carmelo Pesce says that representatives of Cahill have made contact with key stakeholders in the city over the possibility of being involved in the new franchise.

"Tim's very keen to get on board," Cr Pesce said.

"Tim's quite happy to meet up and we'll go from there and catch up some time early in the new year. He's a very big supporter. We have more juniors here than anywhere else in Australia, if not the southern hemisphere, which will bring great value to this area."

However, it is unknown whether Cahill's involvement will be as a player or as an investor or promoter of the club.

St George, Sutherland and Woollongong football associations have already joined forces to support a bid for an A-League club and have received approval to use Remondis Stadium as a home venue from stadium owners Cronulla Sharks.
