Imran, under whom Pakistan won their first and only World Cup title in 1992, said he would try to speak to current captain Shahid Afridi and coach Waqar Younis on the matter.
"I strongly believe that although we won against Sri Lanka, Pakistan is playing one specialist bowler short and needs to include a bowler in place of a batsman or all-rounder," he said.
Imran pointed out that against strong opponents and on a good batting pitch, Pakistan's bowling could struggle.
"So far our bowlers have done well in the World Cup but the team could feel the pinch against stronger opposition. I think they must play either Saeed Ajmal or an extra pace bowler," he said.
The cricketer-turned-politician also maintained that it was no use playing all-rounder Abdul Razzaq at the number eight position.
"Frankly speaking he is being wasted there and he is not the one to take the new ball in the sub-continental conditions. I think Pakistan need to be looking at taking wickets with the new ball instead of giving Razzaq a containing role," he said.
"It is very important for Pakistan to win this World Cup as such a victory would go a long way in clearing the image of Pakistan cricket after the recent controversies and also maybe convince teams to start touring Pakistan again," he added
