Gold Coast United's Miron Bleiberg says he was pleased his side managed to keep another clean sheet yesterday.

United returned to fourth on the table following the scoreless draw with league leaders Adelaide United at Skilled Park and the result was a positive for Bleiberg who did think his team were unlucky no to get a penalty when Reds striker Sergio van Dijk appeared to handball in the second half.

"We wanted to win at home and close the gap on Adelaide, but overall I'm not unhappy. We showed that we are as good as they are and on the positive side we played against the team that is top of the ladder and we didn't lose or concede a goal," Bleiberg said.

"The clean sheet shows that we are resilient and defend well when we have to. Adelaide weren't too adventurous but when you lead the league by as many points as they do, you don't have to go away and attack for ninety minutes. For them this point away from home is a very good one.

"Lady Luck followed them a little with the penalty claim. I didn't see it clearly at the time so maybe the referee didn't see it either and he doesn't have the benefit of six or seven replays. If the referee wasn't sure he can't give a penalty and that's fair enough."
