Michael Vaughan believes Kevin Pietersen is destined for cricketing greatness as long as he maintains the iron-willed determination that has seen him become England's best batsman.
Since making his Test debut just two years ago, the South Africa-born Pietersen, 27, has rapidly established himself as one of the best batsmen in the world, a status reflected by his nominations for Cricketer of the Year, Test Player of the Year and One-Day Player of the Year in the annual International Cricket Council awards to be held in Johannesburg on September 10.
But whether he wins any of those awards, England Test captain Vaughan believes Pietersen is well on the way to securing a place among cricket's elite.
"I see a real drive in him...if he wants to be a true great he can be and at the minute I'm seeing that he wants to take his batting records to new heights, he wants to end up with a career average of 50-odd and probably in both forms of the game," said Vaughan on Wednesday.
Pietersen presently averages over 50 in both Test and one-day cricket.
Vaughan, speaking on a podcast on sponsor NatWest's cricket website ahead of the fourth one-day international between England and India at Old Trafford here Thursday, where the home team will start with a 2-1 lead in the seven-match series, said retaining enthusiasm would be tough for Pietersen.
"He wants to end up with 30-odd hundreds and he's well on his way to achieving that. The big question will come in a year, two years, when he's been playing international cricket for four or five years and it can sometimes feel like hard work.
"That's going to be the real hard ask for him. I'm sure he will do it because he's very driven, he's great for the side, because he scores so fast - I expect a lot more runs from Kevin."
Vaughan added: "He makes it very difficult for the opposing captain because he hits the ball in so many strange areas and he's got that much ability with his hands that he can flick it either side of the wicket at will.
"I guess how good he becomes will be down to Kevin, how many high goals, if you like, he wants to set himself.
"I really do think he's got everything going his way if he really wants to become a true great at the game - I haven't played on the England side with a better player than Kevin Pietersen."
