In-form Melbourne Victory winger Kosta Barbarouses said he has lost respect for Sebastian Ryall and queried Sydney FC's culture following the defender's controversial penalty on the weekend.

Ryall fell to the ground on Saturday night and earned a spot-kick during the Sky Blues' 3-3 draw with the Victory in what was a case of "blatant simulation", according to Barbarouses, who was still seething about it on Tuesday morning.

"You lose a bit of respect for him," Barbarouses said of Ryall, who cheekily flicked Gui Finkler on the back of the head immediately after being awarded the penalty.

"His reaction wasn't great as well, so hopefully karma will come around but that's out of our hands and it's something that they have to deal with in their culture of their team, not ours."
