Pakistan lost in the quarter-finals to the victorious Australians in the World Cup last month, which was jointly hosted by Australia and New Zealand.
After this failure, Waqar submitted a strongly worded report calling for opener Ahmed Shehzad and middle-order batsman Umar Akmal to be dropped from the team.
He accused both players of under-performing and a lack of commitment in the report to the Pakistan Cricket Board (PCB), seen by AFP.
"Yes, its a new era for Pakistan cricket," Waqar told reporters during team's training camp in Lahore.
"These new players will serve Pakistan cricket in the years to come as this is a big opportunity for them," he said.
Waqar said Pakistan needed to now "move on" from the World Cup -- but also stressed that all players needed to learn from their mistakes to improve.
Pakistan open the Bangladesh tour with the first of three one-day internationals in Dhaka next Friday. They also play a Twenty20 international and two Tests.
"This is not my team, neither it's yours -- it's Pakistan team and only those players will play who show the right attitude. I respect those who show (the) right kind of attitude.
