Australia will not allow the emotions of an Ashes series to bubble over, vows captain Michael Clarke.
Michael Clarke insists he will not allow Australia's players to overstep the line when it comes to sledging in the Ashes.
The 2013-14 series in Australia was blighted by a series of on-field exchanges as the hosts ripped through a fragile England, comprehensively winning the series 5-0.
Clarke hit the headlines after he was heard to use foul language when instructing James Anderson to "get ready for a broken arm" in Brisbane.
However, Australia's captain is confident both sides will keep their emotions under control over the coming weeks.
"We have a brand of cricket that if we play that way we play our best," Clarke said on the eve of the first Test in Cardiff. "We have been brought up to play tough competitive cricket on the field, but respect where the line sits.
"I have made it very clear that if someone overstepped [the line in the last Ashes] it was me, I need to be more disciplined and I know I will be.
"They [England] deserve respect. The cricket will be tough but we know there is a line we can't overstep.
"You don't have to say a word to show your intent and play a good brand of cricket. It [sledging] has never helped my game personally.
"As long as the players understand there is a line they can't overstep, they know what they have to do to get the best out of themselves.
"It is not what you say, it's what you do and that's my focus."
Clarke opted against predicting England's side, as he regularly did in pre-match press conferences ahead of the last series, although he expects to face a similar line-up to the one that played against New Zealand in May.
He added: "Everybody knows the England team don't they? It won't change, I think they will stick with team from the last Test with New Zealand.
"I don't think [new coach] Trevor [Bayliss] will make changes just yet."
