West Indies assistant coach Roddy Estwick said his team will have to soon galvanize themselves into action as they cannot afford to make excuses for any more slip-ups.
West Indies slumped to their third defeat of the World Cup against Bangladesh on Monday, dimming their hopes of securing a spot in the semi-finals.
The Caribbean side's tournament has faced a downward spiral ever since they beat Pakistan in emphatic fashion by seven wickets in their opening encounter.
However, they will be coming up against arguably two of the strongest teams in this World Cup - India and New Zealand - in their next two games creating an unlikely scenario for advancing into the knockout stage.
The West Indies' batsmen took advantage of the helpful conditions present in Taunton but a sloppy display in the field coupled with erratic bowling allowed Bangladesh to chase down the target of 322 with just under 9 overs to spare at the back of a majestic century from Shakib Al Hasan.
Estwick outlined the need for the players to stick together as a unit and not find easy scapegoats for defeats.
"We can stand here, saying 'if this' and 'if that' -- we didn't play well, we've lost the cricket game and that's that," he said.
"We've got to come back stronger. We've still got four games left in the tournament and we can't point fingers or apportion blame to anyone.
"We have to stick together, that's how good teams pull through. We've got to stop looking for excuses and start finding solutions."
Estwick lavished praise on the Bangladesh batting line-up, who calmly went about their chase and resisted the initial short-ball barrage opted by the West Indies pace attack.
After recent criticism directed towards the West Indies' tactics of bouncing their opponents out, Estwick admitted the team management was relying on the squad's strengths.
"Four years ago, everyone was saying how exciting and refreshing West Indies cricket looked," he said.
"Hindsight is a wonderful thing. If we'd bowled spin against Bangladesh, everyone would have said that we should have stuck to our strengths.
"Four games down the road, it's the worst tactic in the world. Give Bangladesh credit. They played well and they're an improving side.
"They've played us now five times in the recent past and have beaten us every time. We just have to go away and put our heads together and find a solution.
"We're not down and out yet. We're going to fight and come back harder."
