The Australian team played a big gamble with the opener Usman Khawaja, who was not on the field since the last half of Australia's bowling. The 38-year-old batter was suffering from back stiffness. Even though his absence did not affect Australia while batting, but for former Australian batter, Darren Lehmann, Khawaja must pack up by now. Lehman and former Australian coach Tom Moody attended Australia's ABC Radio podcast, where Lehman said its time for Khawaja to retire. "We needed him out there facing the first ball." Even though Moody didn't go straight to retirement, he called out Australia's cluelessness in waiting for Khawaja after the eight wickets. To him, its was "poor management," and he said, "At the end of the day, to gamble on the fact that he could come back on the field when England is eight down (is a big risk). That is beyond a joke. He is our most experienced top-order player. We needed Khawaja at the front to lead the batting unit into this series." Read also: Why Was Usman Khawaja Not Opening in the 1st Ashes Test? What happened to Usman Khawaja? Australia is leading the five-match Ashes by 1-0, thanks to Mitchell Starc's 10 wickets and Travis Head's demonic 123 runs while chasing. Khawaj did come to bat in the first innings, but got out at 2 runs while coming to bat at 4. Normally an opener, his service was needed in the second innings. While the back stiffness issue was going around, it was learned that Khawaja skipped optional training last Thursday and played golf. However, Cricket Australia Chief Todd Greenberg backed Khawaja, saying that change is necessary. And the back stiffness is not a new problem to him. He even mentioned Starc, who was Khwaja's companion, saying that Starc's performance wasn't affected at all. Speaking to Sen Radio, Todd said, "It's held him in good stead over the last couple of years. A lot of people talk about cricket being played between the ears, and so getting some time away from being in your hotel or training I think is really important. I noticed Mitch Starc played golf with him, so it certainly didn't impact his performance." He added, "Did that correlate to any of the issues? I personally don't think so. I think Usman's a very seasoned campaigner. He knows his body well and he knows how to get himself prepared for cricket, and he's done it over a long period of time. So I think that's drawing a long bow."
