The WesternSydney Wanderers are furious Massimo Maccarone's elbow on BrendonSantalab went unpunished during Friday's 2-0 win over the Brisbane Roar at Suncorp Stadium.
With 11 minutes of the match remaining, Santalab was looking to contest the ball in the air, but the former Italian international only had eyes for the Wanderers striker and caught him with a raised elbow.
Santalab, with blood running from his mouth, protested to the referee but to no avail and his coach Josep Gombau took his complaint up after the match.
"He is upset because it's an action that is not sporting – it's not good behaviour," Gombau said.
"If you ask me from my position, from what I saw on TV and what Santa told me it should have been a penalty and probably a red card."
Gombau cited an incident in his side's 2-0 defeat to Adelaide United in November, when the Video Assistant Referee awarded a penalty and sent off defender Robert Cornthwaite for a handball, and wondered why the same did not happen in this instance.
"The VAR needs to be the same for everyone," Gombau said.
With skipper Matt McKay and Avraam Papadopoulos already missing through suspension for Monday's clash with Sydney FC, in addition to a slew of injuries, Brisbane will dearly hope the A-League judiciary does not find their star striker worthy of any punishment.
Roarboss John Aloisi does not expect Maccarone to face any punishment over the incident given no action was taken at the ground.
"That's what the VAR's for. If the VAR did not pick it up, I don't see how he can be done on that," Aloisi said.
