Vaughan expects from England
Michael Vaughan believes England finally have the firepower to mount a serious World Twenty20 challenge.
Vaughan identified Pietersen's well-being and England's new-look opening partnership of Craig Kieswetter and Michael Lumb as vital components of their campaign in the West Indies.
England have failed to make a significant bid for glory in either of the two World Twenty20 competitions so far played, most recently on home ground last summer.
But former England captain Vaughan expressed confidence that the selectors have hit on the right formula this time.
“This is the third World Cup (sic), and this is the first time I have got excited about the England squad coming into the T20 World Cup.
"For the first time we have guys in the batting with power from one to seven.”
Vaughan sees Sri Lanka's multi-faceted squad, which lost to Pakistan in the final last summer, as the most likely 2010 winners.
England may lack a little of the strength in depth required from their spinners, on pitches sure to favour slow bowling, he fears.
“Maybe we’re a little bit inexperienced in the bowling department, but I think it’s the batting which has let us down in the past,” he added.
“We have had guys who have played in the IPL, which is a big plus to a team going into a tournament like this. I would be disappointed if we don’t put up some kind of fight.”
Vaughan has no qualms about either Pietersen's recent form, or the possibility of him having to fly home to be at the birth of his first child - expected to coincide with the final of the tournament.
“I think he worked something out in (England's Test and one-day series in) Bangladesh," Vaughan said of Pietersen.
"He started to play a little bit better and changed how he played against the left-arm spinner. I think he started to correct a little technical fault he had against them and started to hit the ball in better areas.
"I could tell he was more confident going to the crease. I've just seen him in the IPL, and going in at number three in those last few games he looked a proper player.
"If he plays like he did over there and gets England off to starts and gets to 70 or 80 we will definitely have a good tournament."
Neither does Vaughan expect Pietersen to be put off his game by his impending fatherhood.
"He's here, he's arrived - he will be fine," he said. “He is a crowd-pleaser, an entertainer. He likes to grab the headlines, and I would have thought he will try to do that over the next couple of weeks.”
