Wasim Khan reveals why Naseem Shah decided to stay back in Australia

He is only 16 and reeling from his mother's death last week, but Pakistan believe express bowling sensation Naseem Shah can be a match-winner in the opening Test against Australia.

The exciting teenager is on the cusp of selection for the game at the Gabba in Brisbane starting Thursday after impressing with a fiery eight-over spell against Australia A in Perth.

If he makes the grade, Naseem will join a handful of others to debut at 16, including Indian legend Sachin Tendulkar.

Pakistan has a history of blooding promising players early, accounting for six of the 10 youngest to play Test matches.

But Naseem is also carrying the huge extra burden of his mother passing away.

"He spoke to his family and they said 'this is where your mum would have wanted you to be'," Pakistan Cricket Board chief executive Wasim Khan told the Sydney Morning Herald on why Naseem opted to remain in Australia. "Everyone has rallied around him, keeping a close eye on him, making sure he's okay.”

"He's got a few confidantes in the team that he can go to if he's feeling low or not feeling great. He wanted to stick it out," he added.

Naseem has only played seven first-class games and while selectors clearly like what they see, how he copes in the heat of battle over five days against world-class batsmen such as Steve Smith and David Warner remains to be seen.

Pakistan's squad, hampered by the retirement this year of Mohammad Amir and Wahab Riaz, also includes 19-year-old fast bowlers Musa Khan and Shaheen Afridi.

They also have Imran Khan senior, who back in the Test squad for the first time since their Australian tour in 2017, along with the dangerous Mohammad Abbas and prolific leg-spinner Yasir Shah.
