Pakistan has shaken things up for the final Test against Australia in Sydney, opting for Test debutant Saim Ayub to open the batting in place of Imamul Haq, while fast bowler Shaheen Shah Afridi has been omitted and replaced with Sajid Khan.

These moves signal Pakistan's intent to inject fresh energy after their narrow defeat in Melbourne.

"You always have to look at the bigger picture after a game like the MCG. We've learned the lessons, at least we've put ourselves in those positions from where we could compete in or dominate games," Captain Shan Masood said on Tuesday. "It's now about not repeating mistakes, and if we can put in similar efforts to the one in Melbourne, we'll be winning a lot of Tests."

Despite the Sydney Cricket Ground's reputation for favouring spin, Australia stuck with their lone spinner, Nathan Lyon, keeping their line-up unchanged for David Warner's farewell match.

Captain Pat Cummins expressed confidence in the pace trio's ability to handle the conditions, emphasising their quick recovery from the gruelling Melbourne match four days ago.

With good weather expected and Warner preparing for his 112th and final Test, the stage is set for a captivating encounter. Sydney's history of rain interruptions adds a touch of uncertainty, but both teams are ready to battle for the series finale.

Key points:

Pakistan debutant Saim Ayub replaces Imam-Ul-Haq at the top of the order.
Shaheen Shah Afridi makes way for off-spinner Sajid Khan.
Australia retains their unchanged lineup, including lone spinner Nathan Lyon.
Sydney's weather forecast is favorable, with a medium chance of showers.
Warner's farewell test adds an emotional dimension to the match.
