Don`t boo Nadal, Wawrinka tells fans

Melbourne: Stanislas Wawrinka took Australian Open fans to task on Sunday after sections of the crowd booed Rafael Nadal for taking a medical timeout during the dramatic men`s singles final.

The newly crowned champion said it was "not that nice" that fans booed the Spanish world number one, who was in clear discomfort with a back injury during the second set.

"I think it was not that nice, especially Rafa. We all know that he`s a great guy, a great player," Wawrinka said. "He`s always a really fair player. He always tries his best. He is always fighting."

The Swiss added: "Yeah, was quite strange that the crowd started to boo him."

Wawrinka also had a long argument with the chair umpire when Nadal left the court for treatment, insisting he should be told the nature of his opponent`s injury.

"I just wanted to know what was the problem of Rafa. Because before he asked for the physio, he was checking his feet. I didn`t know really what was the problem," he said.

"Normally when the physio is coming on the court, the umpire always tells the opponent why he`s coming. He didn`t want to tell me, so I got (annoyed)."

Wawrinka eventually won the match in four sets to claim his maiden Grand Slam title, in his first major final.

He said he still planned to play Switzerland`s Davis Cup tie with Serbia, starting on Friday -- providing he survives his raucous celebrations.

"Davis Cup, it`s really important for me. I`m really proud. It`s a big honour to play for my country. So for sure I`m still thinking to go there," he said.

"I don`t know how I`m going to get there exactly, if I`m still going to be alive after tonight, but I`m going to go there... There`s a big chance I get drunk tonight, but we`ll see."
