During a test against South Africa, Smith admitted that Australia’s “leadership group” devised a plan to tamper with the ball.
Former starter David Warner taught batsman Cameron Bancroft how to use sandpaper to rough up the ball, and television cameras later caught Bancroft doing so during the game. Both men were also banned along with Smith.
Smith returned after the ball-tampering episode in the 2019 Ashes Test at Edgbaston and has been booed repeatedly since.
England fans also base the jibes on his tearful press conference in 2018.
“We did something wrong, accept it and move on,” Lehmann said.
“You try to move forward as best you can. You’re reminded of that every day and that’s part and parcel.
“Steve Smith can hold his head up with the way he handles everything.
“The Barmy Army should be better than that. Most of them are very supportive and supportive of what happens in the game.”
