Melbourne Victory forward Kosta Barbarouses has publicly backed Western Sydney Wanderers players in their pay dispute with club management.

Barbarouses went on Twitter to show solidarity for the Wanderers, who are in Morocco preparing for a Club World Cup quarter-final against Cruz Azul of Mexico which may not go ahead unless the dispute is resolved.

Talks between senior players and their club have broken down over how much they should be paid for their CWC matches.

"We stand united behind the @wswanderersfc players and support them in pursuing a fair share of the Club World Cup prize money," Barbarouses said in his post.

Speaking after Tuesday's Victory training session, Barbarouses said the issue would not happen anywhere else.

"We can feel where they're coming from and they've been through so much travel and hard work, obviously committing to both competitions as much as they can," he said.

"They've done a fantastic job and it's only fair they get their just rewards.

"The 10 per cent they've been offered probably wouldn't happen anywhere in the world.

"We're just trying to show our support as players and as a union, as a PFA, to make sure they get their fair rewards."

Finkler the only injury concern for unbeaten Victory

The crisis at the Wanderers is in stark contrast to the Victory, who are unbeaten in the A-League and second on the ladder.

Gui Finkler is their only injury concern after he missed last Friday's 3-0 win over Central Coast Mariners because of a groin problem.

Victory host high-flying rivals Sydney FC this Saturday at Docklands.

"I asked him this morning, he said he was feeling pretty good," Barbarouses said of Finkler.

"I'm not sure if he's going to be alright, but (we're) still a few days out."

"He's been a catalyst for a lot of our attacking play (in) the first round.

"But it's not going to be a long-term thing, so he'll be back with us shortly."

Barbarouses is enjoying a strong season and was the first player of the month.

"I feel very fit, very strong, full of confidence," he said.

"'Mussy' (coach Kevin Muscat) has given me licence to just express myself in the final third."

While Victory will start favourites against Sydney, Barbarouses said his team must play to their strengths.

"We have to be patient - maybe a little more patient than we were on the weekend, when we tried to rush things at times," he said.
