With both sides having failed to make the semi-finals, the match is relatively meaningless in the context of the tournament but having already beaten India and South Africa, Bangladesh will fancy their chances again.
The West Indian side has faced heavy criticism in the Caribbean for their dismal displays in the second-stage Super Eights where they have lost to Australia, New Zealand, Sri Lanka and South Africa.
"We have been disappointing in the first four games of the second round but a team like Bangladesh, for them, every game against a test-playing nation is a big opportunity," said Lara who will quit one-day international cricket after the event.
"We are aware of that and we are going to come out hard and give our very best," he said in a news conference.
Lara is particularly keen to see his senior players finally produce performances to match their reputations.
"Including myself, we haven't been performing like the senior players for other teams.
"If you look at Australia, South Africa, Sri Lanka and New Zealand they are guided by their senior players.
"We wanted to produce more, we all know the importance of the likes of Chris Gayle and myself and players who have played in excess of 100-150 one-day internationals.
"A lot of responsibility is in our hands to come up trumps and we didn't. It was disappointing for us and we didn't act together at the right time but we have to move on and focus on the last two games," said Lara.
After facing Bangladesh, West Indies finish off their campaign against England on Saturday, also at the Kensington Oval.
The seven-week World Cup, the first in the Caribbean, reaches its climax with the April 28 final in Barbados.
