Pakistan picked three rookie pacers for the Australia tour but they leaked a lot of runs in both the Test matches. Australia won both matches by huge margins.
Waqar, a former Pakistan captain, however, said Naseem Shah, Musa Khan, Muhammad Hasnain and Shaheen Shah Afridi were all the future assets of Pakistan cricket.
"I think once they play a few matches more over a period of a year they will get better and Shaheen is an example of this."
Pakistan will next take on Sri Lanka and the first Test begins on December 11 in Rawalpindi.
