Australia head coach Andrew McDonald on Saturday showered praise on David Warner and said that he is probably the greatest all-format Aussie player. Speaking to cricket.com.au ahead of the third Test match against Pakistan, McDonald said that Warner's retirement from the Test format would be a great loss for the Aussie squad. The Aussie head coach added that it would be hard to find the left-handed batter's replacement. "In time, he will probably go down...but probably at the moment as it sits, he is probably our greatest ever all-three format player. He is going to drop out of one of those formats in terms of Test match cricket. He will be a loss. I know that people have been gunning for him for a period of time, but for us internally, we have seen the great value in what he brings to the table, hence why we have kept picking him. He repaid a bit of that faith in the first Test match. He's going to be hard to replace. Someone who strikes at 70 averaging 45, and most ever runs as an Australian opener," McDonald said.
