He was grabbing his private parts at me, numerous times, and I asked him if he had an issue Lleyton Hewitt

Hewitt and Coria traded insults after their 173-minute battle, with Coria revisiting stories concerning Hewitt that first surfaced during the Australian Open with on-court incidents with Argentinians Juan Ignacio Chela and Nalbandian.

"As a person outside the game it's one thing, but on the court I really felt like killing him," said Coria.

"Rafael Nadal jumps and does a lot of gestures on the court, but he doesn't celebrate your own mistakes, whereas Lleyton cheers for other peoples' mistakes and he's very aggressive.

"It's very difficult not to feel provoked and not to get into his game, but as a person I would rather not win a single tournament in my life than be like him."

A dumbfounded Hewitt said: "If the worst thing I do is say 'come on' out on the court, I don't think it's that bad compared to the guy spitting in the referee's direction when he wasn't happy with the call.

"He wasn't happy with the court surface, and he tried hip-and-shouldering (bumping) me at the end of the first set and he complained the whole day. I'm not quite sure what his issue is."

He added: "I asked him at one stage when he was grabbing his private parts at me, numerous times, and I asked him if he had an issue.

"I'm still struggling to deal with what I actually did wrong. To be perfectly honest, he's arrogant, and he lost the match today and he's looking for every excuse in the book. He's a sore loser.

"It didn't feel like a tennis match, but it was dumb by them. Very rarely have I lost matches when people try to get into my face.

"What Chela did (spitting) at the Australian Open was disgraceful and it's carried on and I don't think David Nalbandian is the cleanest guy about the hip and shoulder (bump) at the Australian Open.
