To be honest I agree with @MusaPk. In the three tests that Pakistan has played in Australia, I think Warner got about 5-6 chances in the 6 innings that he played in these 3 tests. He scored so many runs after he got them second chances. He would have probably scored half the runs that he scored in this series than he did after getting all the chances. Shaheen Afridi and Jamal were getting the fielders the chances in the early stages of the match with the new ball and Warner would have gotten out early on so many occasions.
But despite all that he is still an Australian legend I think it will be hard for Australia to replace him.
The Pakistan players should improve their game,because the Australian had the capability to get back in the short period in the cricket game.Because we never forget the game of Australia woman players against India in the second T20 match,they had won the game with the one over left and win by 6 wickets.This was the unique come back after the same team had loss the first T20 by the 9 wickets.Warner was the good player in the various sections.He dominated the Pakistan team in this match by scoring the half of the runs in the complete series.Australian already had good record against the team Pakistan in all format.
