"We are still in a must-win situation when we go into the last game to fulfil our dream of the first ever one-day series victory," said a delighted Bashar at the post-match briefing.

The Tigers skipper expressed satisfaction over his team's overall performance in the match and said that they were now quite confident to win the fifth and final one-dayer against the Africans on Monday.

"The way we fought back in the series is something rare in our cricket. We made some mistakes in the previous matches, even in the third one-dayer which we won by 40 runs. But I must say we have had a much better show today," he said.

The captain had special words of praises for his two left-arm spinners Manzarul Islam and Mohammad Rafique who turned the day-nighter on its head by evenly sharing eight wickets between them.

"There is no doubt about the ability of Rafique, but Manzarul really surprised us with his brilliant performance," he said.

Manzarul, who also became the first Bangladeshi to win successive man-of-the-match awards, was delighted as well but he said that he was looking forward to the last game.

"I will be a happy man if I contribute something for my team in the series decider," said the soft-spoken spinner.

"Giving the breakthrough was important but I think taking the wicket of (Tatenda) Taibu was vital," he added.

Taibu, the Zimbabwe captain who now has to regroup his side in the series decider, admitted that the two Bangladeshi spinners made the difference.

"But I believe that everything is not lost yet. We can still win the series from here," said the wicketkeeper.

Toss has so far been playing a 'decisive role' in the series and teams that have called the coin right and batted first have won in the first four games.

32-year old Bashar responded with a big smile when he was asked about the coin factor.

"So far the teams batting first after winning the toss have been successful in the series. Of course, we were lucky enough today to win the toss because it was a big advantage in the day-night match. But we are not scared to batting second if needed," he said.

Replying to a question, the premier Bangladesh batsman said that at no point of the game were they in a position to lose the match even when the two Zimbabwean openers were going great guns.

"Their opening pair batted brilliantly, but we were confident that the match would turn in our favour once we got the breakthrough. It was difficult to bat against the spinners under lights," he said.
