The emergence of South Africa-born Craig Kieswetter has drawn much of the attention over the last fortnight.

England left Dubai for Bangladesh on Sunday having gleaned plenty of positives from their drawn Twenty20 series against Pakistan - but the biggest impact may have been made by a man who took no part in either match.

Paul Collingwood, England's captain in the shortest form of the game, will hand the leadership to Alastair Cook when the team touch down in Dhaka, having presided over an entertaining 1-1 draw against the world champions.

But before passing the baton to Cook, Collingwood had time for an assessment of the squad's progress.

Graeme Swann, whose measured bowling earned him the man of the series award, is sure to have impressed, as did big-hitting duo Eoin Morgan and Kevin Pietersen.

But it was the emergence of South Africa-born Craig Kieswetter which has drawn much of the attention over the last fortnight.

The wicketkeeper-batsman's fine form on the Lions tour of the UAE, including a knock of 81 against the senior side in a warm-up match, earned him a last-minute call-up to the one-day side, a move which earned Collingwood's blessing.

The captain said: "The way he played against us, and the way he played for the Lions against Pakistan A has opened everyone's eyes and he deserves inclusion into the senior squads.

"He's an exciting player and he hits the ball extremely hard, which is great for one-day and Twenty20 cricket. He deserves his chance."

Despite the fact he has been keeping wicket for the Lions, and also does so for Somerset, Kieswetter's emergence does not appear to directly challenge Matt Prior's place in England's limited-overs set-up.

Prior is Andy Flower's first choice gloveman in all three formats and Collingwood was fulsome in his praise of the Sussex man earlier this week.

Instead, it is Kieswetter's fearless ball striking at the top of the order that the England selectors covet after their opening partnership misfired on both occasions against Pakistan.

Jonathan Trott is likely to get more chances but Joe Denly, whose double failure in Dubai took his Twenty20 record to just 20 runs in five innings, may be sacrificed.

When asked about the Kent batsman's struggles, Collingwood was supportive but equivocal.

"I'm sure he's disappointed with his form because we've seen what Joe can do in county cricket," he said.

"His domestic record is very good but batting at the top of the order is a confidence thing, and if you get one innings when you get it away, you get the ball rolling.

"There are things we've got to improve on before the Twenty20 World Cup, but Joe is a three-dimensional cricketer.

"He didn't get a chance to in this series but he bowls useful leg-spin, he's good in the field and he's a great lad to have in the dressing room. Let's hope his form turns around."

One player who does appear to have recovered from some indifferent form is Pietersen, who put a subdued tour of South Africa behind him to hit 43 and 62no against Pakistan.

Reflecting on the renewed confidence of the side's premier batsman, Collingwood said: "KP really looked back to his best again and that is a crucial thing for England."
