In the first three games, the toss winning sides have batted first and won and that is why both Bangladesh and Zimbabwe will be keeping one eye on the flip of the coin today hoping luck will go their way when they meet for the fourth encounter of the five-match series at another featherbed of a track at the Bangabandhu National Stadium.

But Bangladesh coach Dav Whatmore and captain Habibul Bashar said the win in the third match in Chittagong had given the Tigers the confidence to face any situation head on.

"This is cricket where winning the toss and losing it are very much parts of the game. I think it looks a little bit harder to chase runs if you get a total in excess of 230 or 240. But I think we are capable of winning a match batting second and we are not scared of chasing," said Whatmore whose side trail Zimbabwe 1-2 in the series.

"The morale of the team is high because they fought back to win the third game. We are still alive in the series and it's a vibrant feeling. We want to do everything we can to make the last one-dayer on January 31 a grand finale," said the confident Bangladesh coach.

"The last game was also a crunch one as well and we realise what we have to do and we'll have to win the series the hard way. We have another crunch match tomorrow and I think we are good enough to win it," he added.

Whatmore said that he was not worried with the problems faced by the middle-order which saw Bangladesh struggling to accelerate the score in the in the previous games.

"It's not uncommon in the other teams of the world too. If you pick up a wicket or two that's the best way to slow down the run rate. It's not exclusively a problem for us. It was not always possible to bat well throughout the 50 overs and you know that there will be some little hitches when you are batting."

Zimbabwe captain Tatenda Taibu and Elton Chibumbura have given Bangladesh most headaches in the series and Whatmore said that they were working on ways to stymie the effects of the two.

"It is in the end overs that they have been most lethal so we have a few plans for them."

Tigers skipper Bashar emphasised on not repeating mistakes from earlier games.

"I think we lost the first two games because of one or two mistakes. We can't do anything about the toss and that's why we should focus on our own performance and we will have to win the match batting second if necessary."

Bashar said he preferred to keep the batting line-up flexible and was keen on seeing partnerships developing in the middle.

"It is not always good to go for big shots. We should also concentrate on singles sometimes."

Taibu's team practised under lights in the afternoon and the 21-year old was showing no signs of any pressure after the defeat in the third game in Chittagong.

"We play the game to enjoy it. We play at our best when we enjoy the game and we are going to try and do the same thing. I think pressure is always there but the boys have coped with pressure very well. So it will be no different tomorrow," he said.

"I reckon 270 will be a good score, batting first," added Taibu when asked what could be a reasonable score to defend.

Taibu also felt that the Bangabandhu Stadium was a lucky ground for them.

"Bangladesh beat India here and we beat them here too. We played better Test cricket here and they played better in Chittagong. So it's also a good ground for us."
