Pietersen was England's leading run scorer with 294 at an average of 29.40. Here are his scores in the five Tests:
Brisbane: 18 & 26
Adelaide: 4 & 53
Perth: 19 & 45
Melbourne: 71 & 49
Sydney: 3 & 6
Tufnell cited Pietersen's performance in the third Test in Perth, where he looked set for a big score after amassing 45 runs in the second innings, as well as the second Test in Adelaide, where he was after out for just four in the first innings.
"At Perth, he hits one ball over long off for six and then, the next ball, he hits it straight down the fielder's neck," said Tufnell.
"He comes in at Adelaide and you're saying, 'come on Kev, get us out of this hole', but he comes down the wicket and flicks Peter Siddle to one of the two men on the drive at mid-on.
"Why is he doing that? Great players wouldn't have played those shots."
Former England captain Michael Vaughan defended Pietersen's attitude and style of play, calling him "a genius".
"You have to give the likes of Pietersen, with the ego and the flamboyancy, the freedom to play," said Vaughan.
"You have to allow him to play in that fashion as that's when he's at his best. He averages 47 in Test match cricket. He is that type of player.
Don't make Pietersen scapegoat - Vaughan
"As much as he's got out playing terrible shots throughout his career, he's a genius.
