Glenn McGrath is confident Australia have devised a plan which will derail Kevin Pietersen's hopes of inspiring England to Ashes glory when the first Test gets under way at Lord's on Thursday.
Pietersen showed his liking for the Australian attack during the recent one-day internationals between the two countries, most notably when hitting a hurricane 91 not out at Bristol.
It was sufficient to earn the Hampshire batsman promotion to the Test squad ahead of the experienced Graham Thorpe.
But McGrath, who needs one wicket to reach 500 in Test cricket, believes his side can exploit flaws in Pietersen's technique in the longer version of the game.
McGrath said: "It has been good to see Pietersen before the Test match. The way he plays, I think he is very much suited to the one-day game.
"It will be interesting to see how he goes on at the longer format of the game. The fact that he averages 50 in first-class cricket shows that he can handle it pretty well.
"But we have seen a few things in the last few weeks to enable us to make a plan up of how to bowl to him that we think will be quite successful this summer. It's been good to see how he bats."
There is a theory Pietersen is weaker playing on the off side, and McGrath admitted: "I am sure we will work out where he doesn't like hitting the ball and try to keep it there.
"We have picked up a few things in the one-dayers, certain shots he plays, and I think we've got a pretty good gameplan ready to go from what we have seen."
Pietersen's debut has evoked memories of the way Worcestershire batsman Graeme Hick was built up at the beginning of the 1990s only to never transform county success onto the international stage.
Former Worcestershire player McGrath said: "Hicky is a quality batsman but Pietersen seems to be a bit more of a confident character than Hicky is. Mentally he is probably a little stronger.
"He seems a pretty aggressive batsman. Hicky to me was class and has got all the shots, textbook stuff, whereas Pietersen is not quite of that same mould."
While Pietersen has grabbed many of the pre-Test headlines, McGrath feels paceman Steve Harmison may hold the key to whether England claim the Ashes for the first time in 18 years.
The Durham player has improved significantly since being part of the England side which last did battle with Australia two- and- a- half years ago.
McGrath said: "Harmy to me is a massive key for England. If they are to do well against Australia, then he has to perform at his best - maybe the best he has bowled in international cricket. I thought he started the one-day series very well but in the last few games he didn't seem quite the same so whether his confidence has dropped a bit, I am not sure.
"But for me, he is a huge key for England and a lot rides on how he performs in this Test series.
"Cricket at this level is all about confidence. When you are confident of doing well, everything is good. When you are not confident, all of a sudden people worry about your technique and this and that.
"It is not about technique. Everyone has got the technique. Everyone can perform at this level. It's just whether they believe it on that day or not."
McGrath added: "Harmy looked a quality bowler two-and-a-half years ago in Australia but just bowled too many bad balls per over. The radar wasn't quite switched on and he had run-up problems in the one Test in Perth.
"He has sorted those things out, hits the right areas a lot more and is more consistent. When you bowl with that pace and bounce, if you get it in the right area, you can cause problems."
McGrath admits it will give him immense satisfaction if he achieves his 500th Test victim at Lord's.
He said: "To have the opportunity to take the 500th at Lord's will be very special. I could not have scripted it better than to finish the New Zealand tour on 499.
"I am confident that I can pick up a wicket early but I'm not really too worried who it is.
