Graeme Smith suggested England captain Michael Vaughan would regret the revelations of on-field skirmishes in his new book after learning from experience.
World XI captain Smith advised players not to tell tales out of school after the first day of the Super Test at the SCG, during which he has Andrew Flintoff - who, according to Vaughan, he branded a "big baby" throughout last winter's tour of South Africa - and Steve Harmison under his charge.
There was plenty of animosity in England's 2-1 Test series success in South Africa and Vaughan revealed Smith called him "queer" on a regular basis.
The relationship was not helped when, during a fourth Test hearing into comments by Vaughan relating to the consistency of the umpires' decisions on bad light, Smith stood as a witness.
Smith, who detailed the sledging he received from the Australians on his debut in a magazine article three years ago, said: "It is sad when you take things that happen on the field off the field. You sometimes say things you regret.
"Sometimes things get said and done out in the middle. We are all playing for our countries and it is tough.
"Once you get to know one another you get on well, it is hard to judge people just on a cricket field.
"I was naive maybe talking about the Australians as a young guy. If I could have that time back I would not do the same thing. It's private what happens on the cricket field."
The thing I particularly like is the utter hypocrisy the loud-mouthed tosser displays by saying "It is sad when you take things that happen on the field off the field" - this is the person who tried to get Vaughan banned by being a witness against Vaughan. According to Vaughan's book, when Smith was being called as a witness to disprove Vaughan's comments about the South Africans asking for bad light, Vaughan said "Well, he did appeal for it" while Smith claimed he hadn't, insisting all he'd said was that his outfielders were struggling to pick up the ball... Apparently Vaughan calls Smith 'the Witness' now. Ironic that after all the names Smith has called the England players there are a plethora of a good names you could justifiably call him.
