Bangladesh bowling coach Courtney Walsh warned that bowling conditions in the England would make the upcoming World Cup a tough test for his side.
"It will be a big challenge," Walsh told reporters in Dhaka. "There are going to be some good cricket wickets, which are batting-friendly. We have to be intelligent, and try to execute well.
"We have to read the conditions and the surfaces we play. Some places the ball might swing more than the others. We have to assess when we get there."
Walsh, who played four World Cups for the West Indies between 1987 and 1999, tipped the bowlers to rely on their variations as the wickets are likely to be flat throughout the tournament.
"Most of the wickets will be docile and flat. We have to work on our variations and execution," he said.
"Everybody studies one another these days. So they know our strengths and weaknesses. Likewise, we also know theirs."
Walsh will be overseeing a Bangladesh pace bowling unit already grappling with injury problems.
The Caribbean star revealed that three of his five charges – Mustafizur Rahman, Rubel Hossain and Mohammad Saifuddin – were injured.
"We need to get them back into bowling, within the right frame of mind, and be sharp enough to do a bit of bowling in Ireland and be ready for the World Cup," he said.
Bangladesh will open their campaign against South Africa on June 2 at the Oval.
