Justin Langer feels David Warner can rediscover top form after the opening batsman ended the Ashes campaign with a cumulative total of 95 runs in 10 innings.
Warner's woeful form across the series was characterized by his obvious troubles in negotiating the nagging line opted by Stuart Broad with the new ball.
He fell victim to Broad's shrewd bowling seven times and endured raucous jeers from the hostile crowd, who did not hold back trying to remind him of his involvement in the ball-tampering scandal last year.
But Australia head coach Langer stressed Warner was still very much part of the plans heading into his side's home season.
"I've learned over a long period you never write off champion players, it doesn't matter what sport, you never write off champion players," said Langer, after Australia retained the urn following a 2-2 result.
"He had this series, it didn't go to plan, but he's seen how successful he's been and the impact he can have on Australian cricket teams winning, so I'm confident he'll come good."
Meanwhile, Langer seemed a bit hesitant in fully committing to Warner making a resounding comeback in red-ball cricket and stated the 32-year-old let Broad exploit his weaknesses.
"Actually, I'm hopeful he comes good. Talking frankly, I thought he let Stuart Broad get into his head and I think he thought way too much about it."
Langer admitted Warner would be content with heading back home and spending some time away from the game.
"In this instance I don't think David solved the puzzle, and he'll be the first to admit that," he said.
"He'll probably be very relieved (when) he gets on the Qantas flight knowing he doesn't have to face Stuart Broad for a while, I reckon."
