Argentina's David Nalbandian who lost 6:4, 3:6, 6:2, 6:7, 8:10 to American John Isner at Australian Open, commented on umpires' decision at 8All point.

“I asked for HawkEye and he made an overrule because of the lineman call out. He told me he overruled it. And I say, Okay, I see the mark and ask for a challenge. I was refused, he told me it's too late.”

“It's ridiculous playing a tournament like Grand Slam with this kind of umpires. What do the umpires need, press? Name? Be on the picture tomorrow? Incredible. Anyway, I didn't lose for that, but that's was very bad situation.”

“I've never seen an umpire doing a bad job like that. So ATP have to check what they doing for the umpires,” Australian Open quoted the player as saying.
