Kieswetter makes instant impression after roaring among Lions

Kieswetter was only parachuted into the one-day squad for Bangladesh at the last minute after advancing his case with some sterling performances for the Lions but he stole the show in the tour opener, scoring six sixes and 14 fours in his side's total of 370-7 in 50 overs.

Paul Collingwood also found top gear as he too peppered the boundary on his way to a 74-ball 109 as England triumphed by 112 runs. But, while Collingwood's contributions in limited-overs cricket have become par for the course, newcomer Kieswetter appears to offer something new at the head of the innings.

That means space may have to be made for the Johannesburg-born player across the formats.

"We knew he could play like that from the Lions games but to do so on your first official England game, even though it wasn't a full international, is fantastic," said Cook, captaining his side in 50-over cricket for the first time.

"He didn't look too flustered, took the right options at the right times and played a fantastic knock.

"He's got a very good chance (of breaking into the first XI), he's done very well to push his name forward. It's going to make for some tough selection problems down the line, even on this tour, but the ultimate benefit of that is that the England side is improving."

Cook added: "The way we started with Craig was fantastic and he'll take the headlines but Colly was fantastic as well.

"Every tour we set out to improve from where we are at the start of the tour and people coming in and doing it like he has helps us to do that."

Cook also helped himself to a half-century, scoring 56 at better than a run a ball in a first-wicket stand of 127 with Kieswetter.

But there were some disappointments, with Kevin Pietersen facing just a ball as he received a dubious decision and England toiling without success for extended periods in the middle of the BCB's 258-9.

Indeed, of the bowlers only Graeme Swann, who returned 4-44, will be entirely satisfied.

In regular captain Andrew Strauss's absence, Cook is determined to keep performance levels high at all times.

"To put on 370 in new conditions was excellent," he said. "But we can't rest too easy, there are things to work on.

"Our fielding wasn't as good as (the standards) we've been setting recently on a tough outfield.

"That's an area we can work on. If we were happy with what we'd done (yesterday) in all areas then we wouldn't improve as a side and we need to improve over the next couple of weeks.

"The lads are very happy with what they've achieved but there is more to come."

Indian Premier League chief Lalit Modi has insisted this year's tournament will go ahead in its home country as planned, accusing the media of overplaying security fears.

Australian Cricketers' Association chief executive Paul Marsh had earlier revealed an independent report into security for the league had shown up some "serious concerns".

But Modi said: "We are going to have the tournament in India. I can't see any reason why we should move it at this point in time.

"The media is reacting to every fringe group saying security is a problem."
