Despite scoring 81 runs in the second innings of the second cricket Test between India and Australia in Brisbane, Dhawan is under pressure after failing in both the innings in the next Test in Melbourne.
And Moody feels Dhawan needs to work on his basics to pile up big runs in the longest format of the game.
"The frustrating thing for Shikhar Dhawan is that he has got starts on a number of occasions on this tour. He has got himself in and not gone on to make those big hundreds which is obviously the hard part," Moody said after Australia regained the Border-Gavaskar Trophy with a 2-0 lead in Melbourne.
"Moving forward it is important for him to have a better understanding of his off-stump. For an opener particularly, that is very important in places like Australia, South Africa or other countries. He should always look to play positive cricket but that ability to leave the ball is very important too. When the ball is in that area, that corridor of fourth or fifth off-stump, knowing when to leave it makes all the difference," he opined.
"He's got a couple wrong decisions and gotten himself out at the wrong times on other occasions. There cannot be a question over his talent or that ability to play the free-spirited game at the top of the order. And he shouldn't be asked to curb it either because he isn't getting runs.
