Usman Khawaja believes David Warner is capable of breaking Brian Lara's record Test score at the WACA on Saturday after the Australia opener put on a remarkable show on day one against New Zealand.
Warner's rich vein of form continued when he scored his maiden Test double-century in Perth and Khawaja (121) made his second ton in as many Tests as Australia racked up 416-2.
The brilliant Warner scored a century in both innings in the hosts' first-Test victory last week and his scintillating 244 not out on Friday was the most runs scored by a batsman on day one of a Test in Australia.
Given the form Warner is in and the rate he scores at, Khawaja thinks West Indies legend Lara's mark of 400 - set against England in 2004 - could be in danger on day two of the second Test.
Khawaja said: "I hope [he can break the world record]. I think Davey will probably be thinking about 250 first, and then 300, but if anyone can do it it's probably him,
"But at the end of the day, we're going to have to see how the game's going too. We'll always be a team first, so we need to see how it's panning out.
"But if anyone can get 150 in not much time it's Davey, so I'd love to see that.
"[His innings] was probably something that only him and maybe a few others around the world could do. It was great to have the front-row seat to him smacking them around everywhere."
Warner and Khawaja shared a century stand when they both reached three figures on day one of the first Test and the left-handers put on another 302 for the second wicket in Perth after Joe Burns was dismissed for 40.
Khawaja said: "I think Davey did brilliantly in that he didn't actually lose his head - he just kept hanging in there and when he got a bowler that he liked, he really took them down.
"That's how the game ebbed and flowed; we got runs in clusters, where it's not usually like that at the WACA.
"Credit to Davey. He's learnt his game. He knows he's got the explosiveness up there with the best cricketers in the world, but he doesn't always have to use it. He's learnt that now. He picks and chooses when he needs to use it."
Khawaja was dismissed late on day one after being dropped by wicketkeeper BJ Watling and also having a stroke of luck when he was caught behind off Mark Craig, but was given not out with New Zealand having used all their reviews.
