Warner scored an incredible 258 runs from 137 balls in his final two matches.
Sydney: Australia's Twenty20 expert David Warner has credited former chairman of selectors Greg Chappell for his recent success in Champions League Twenty20 and said he is now targeting a Test debut next year.
Warner had an incredible run-scoring feast during the CLT20 with New South Wales (NSW), scoring 258 from 137 balls in his final two matches.
The 24-year-old left-hander feels Chappell, a former Australian skipper, was instrumental in improving his batting technique.
"Chappell has been wonderful in the way he has guided me through with my batting in the last few months. I think he is a great cricketer and I've learnt a lot from him," Warner was quoted as saying in the Daily Telegraph.
Warner, who is the first player to score back-to-back centuries in the game's shortest form, is now seriously developing himself for the longer format.
"I started my career with T20 and it has helped me develop as a player," said Warner.
"However, my goal is to make my Test debut next year. T20 is a great forum to score runs and a stepping stone to ODIs and Tests. It's important that a player is not hemmed in by one particular format."
Warner is now in South Africa, where he will be part of Australia's squad for the 50-over and Twenty20 matches.
