''Greg Chappell, one of most stylish of all batsmen, and now India's coach, believes batsmen should look for the full ball, which means an initial transfer of weight onto the back foot, which in turn provides the natural foundation for moving forward on to the front foot,'' Brearly wrote in his column for the 'Observer'.
''I think that Pietersen follows this advice. He trusts himself to deal with the short ball. Anything pitched up to him, he is ready to move and utilise his great power. But he doesn't move too soon.
He is rarely out of position with his front leg,'' he said praising the explosive England batsman.
Brearly said Pietersen was a genius in the making and a few more tests against pace will confirm this.
''Pietersen is, or has the makings of, a genius. We have to see how he fares against sides with real depth of fast bowling, but I'm sure he'll do better than most even if some team manages to match the great West Indies sides of the 1970s and 80s,'' he said.
The former captain felt England would do well not to put pressure on Pietersen to perform in all the matches and said the right-hander was a treat to watch even if he got out early.
''We can't rely on Kevin Pietersen to score a hundred each time he bats. But what a player he is,'' Brearly said.
''Pietersen uses his stature to full effect. He dominates the crease, all 6ft 4in of him, powerfully present. His batting is based on getting on to the front foot. Like all great players he seems to have time to get forward but also to play off the back foot,'' he added.
