Jamie Siddons, the Bangladesh coach, is chasing a dream series win over England on Monday after his side's historic victory in the second game at Bristol.

So often a tense onlooker, Siddons was in a bullish mood at Edgbaston ahead of the series decider. Until Saturday's triumph Bangladesh had never beaten England in any form of the game but now stand within one match of a series win that seemed unthinkable after the opening game.

"It would be a bit of a dream for us but it's not impossible," Siddons told PA. "We'll go out on Monday, do what we've been trying to do the last few games - either putting a score on the board or chase down a score - and anything is possible.

The sides have now played each other over four Tests and five ODIs this year - with England winning every game until Saturday - and Siddons feel he's spotted some weaknesses for his side to exploit.

"I've said before there were a few chinks in the armour of this England team and I guess them leaving a few players out of their side weakened them a bit. But some things have been exposed and that will get written about and talked about. But they are still a very good team, so are Australia and now we are getting there."

Having waited all year for a victory Siddons has had a tough job raising spirits in the squad but with one victory now secured he hopes they can turn their fortunes around.

"We've had a lot of losses and a lot of heart-ache along the way but we've won a game now and hopefully we can continue playing some good cricket and put ourselves in a position to win some more games," he said. "The way we built up to this win was important to me, not just the win itself. It wasn't just a flash in the pan, we've been building up to this and we have to keep playing good cricket. The jubilation has already gone I guess and we're getting ready to play another game on Monday."

Meanwhile Paul Collingwood has called for England to regain their intensity to avoid their first series defeat in one-day cricket since losing to Australia 6-1 last summer. England looked lacklustre as they slumped to a five-run defeat on Saturday and Collingwood feels England need to recreate the spirit that delivered victory in the first three ODIs against Australia this month.

"We need to get back to the same intensity as we had at the start of the Australia series," said the allrounder. That's when we were putting the opposition under the most pressure and that's when we played our best cricket.

"It's probably more the mental stuff than the technical and it's something we talked about in the Australia series after going 3-0 up. That was a position we hadn't really been in before against Australia and we really wanted to get a ruthless streak going. Ruthlessness is a skill in itself and it's something we need to keep improving on."
