Wanderers appeared on the wrong end of two VAR decisions in Sunday's 2-0 loss to Adelaide United.

Adelaide earned a penalty in the first half after a Robbie Cornthwaite handball was spotted by the VAR. However, the controversy was that Cornthwaite was given a second yellow card for the offence.

Baba Diawara missed the spotkick but United's opening goal was controversial when the VAR allowed it to stand despite the Senegalese striker appearing offside and interfering with play before Ryan Kitto scored.

"For me it's difficult," Gombau told Fox Sports.

"I think it's killing a little bit the game, in my opinion because the game stops and the referee comes.

"We've seen in this round, five games, three or four players sent off and penalties, alot of things have happened.

"I don't think it's helping the game."
