Australia coach Darren Lehmann believes that there is no need for a meeting between himself and England coach Andy Flower to set sledging boundaries.

The notion arose following Aussie batsman David Warner's comments that the dismissals of England's Jonathan Trott in the first Test were "pretty poor and pretty weak".

Following his remarks, England confirmed that Trott will not feature in the remainder of the Ashes series due to a stress-related illness.

"Trott has gone home and we hope he gets well soon," Lehmann told radio station 5AA. "We do care about that but we're still going to play really hard cricket."

"I just know we copped a lot in England and we didn't shy away from that. That's what happens when you go away, so I don't see what the difference is from England to here.

"We're on the other end of it, that's just the way it goes. Both teams play hard and as long as it stays on the field I'm happy with that."

The second Test gets underway in Adelaide next week.
