Western Sydney coach Markus Babbel has called for A-League refereeing standards to improve after his side’s loss to Perth Glory.

The Wanderers led for much of their clash before succumbing to a late blitz of goals from the A-League leaders.

But there were queries over a potential offside or foul in Diego Castro’s first goal, while the Glory matchwinner was courtesy of a dubious penalty, which Andy Keogh won.

Babbel called upon journalists and football experts to raise the issue of refereeing.

“If I say that, what I think, what is in me then I get a (fine) or I get banned, so I’m not talking about it,” Babbel said post-match.

“But you have the chance to talk about it because I saw a fantastic game, two games played a really good style of football I think for the supporters, for the people in the stadium, was a fantastic game to watch.

“And now is the chance for you there to talk about it because this is not professional-like. The quality — if I see all the games, not only watching our games, I see many, many more games — this is not good enough. That’s it.

“So now is the chance there to talk about it because if I say something, I get the (consequence) and I want … to have success.

“So you journalists, you have experts, many, many people talking about this fantastic sport. But talk about this as well because this is a problem. It’s not only a problem for us, it’s for everyone a problem today, okay — for us.”

Babbel said he struggled to see how there were “so many mistakes” in the A-League, given the presence of the VAR.

“This is what I don’t understand. Now you have the help with the VAR and even then you do so many mistakes,” he said.

“This is very hard to accept and especially if you have a team on the pitch like today with so many young players that deserved definitely more. But what will you do?”

When asked whether he would take the issue to the “head honchos”, Babbel said they would have to be “blind” not to see there was an issue.

“If they don’t see it, then they’re f***ing blind,” he said.

“So they have to see it and they have to do something because the quality is not good enough.

“I know it’s not an easy job, don’t understand me wrong, but if you decide to do it, then you have to know, it’s similar to my job, to the players, we get criticised. And now is for me, too many mistakes.

“And you can see it, but I don’t know what’s going on in their heads, they’re making decisions — you can’t understand this and it’s very hard to accept and they also have to improve.

“We have to improve, I have to improve — but they also have to improve. And this is now a good time for you, for all the experts in the league to talk about it — because if you’re not talking about it, nothing will change … that is what I mean.”

When asked about the Castro goal, Babbel didn’t want to dwell on the issue but emphasised the need to “talk about” the league’s refereeing.

“Offside, maybe foul — I don’t know but the game is now like it is, so now we have the chance to talk about it,” he said.

“We can’t change it — we can say (this or that) … But nothing will change, we have zero points.

“And now is the time to talk about it because the season is still going, this is not the end of the season, so start now and I hope they also will improve.”
