Australian great Ricky Ponting has no doubt David Warner can be more hit than miss in Test cricket.
But Ponting says there will always be questions whether Warner has the temperament to convert explosive short-form batting into Test knocks of substance.
Ponting says the same questions were asked of Adam Gilchrist before the ex-wicketkeeper answered them with emphatic Test scores.
"No-one probably thought that Gilly would have the temperament to be able to survive and make as many hundreds as he did in Test cricket. He found a way and he did it," Ponting told reporters on Tuesday.
"Sure it's a little bit different for Dave because he's an opening batsman in Test cricket.
"But the bottom line is, he's not playing any more short-form games than the majority of our players."
Ponting said Warner, dismissed for fewer than 30 runs in 12 of his 17 Test innings, faced a challenge to adapt to Test matches.
"What he has to be able to do is adapt himself very quickly from the changeover of formats and find a way to be a very consistent run-scorer for Australia in Test match cricket at the top of the order," Ponting said.
"That is what we all have to do and it's not an easy thing to do especially when you play the way he plays.
"But what I know about him, if he's playing well and hitting the ball in the middle of the bat, then he will set up a lot of Test wins for Australia in the future."
