Bangladesh Under 19s won by 9 wickets (DLS Method)
But having witnessed the angry reaction in Australia to Smith and Warner's conduct, Langer said it would be hard to imagine any English taunts could be worse.
"Well we can't control the crowd. What I do know? It may heat up, but it won't be any hotter than it was 12 months ago," said Langer at an Australia training session.
"I've never seen anything like it so the boys are very well prepared," added the former Australia opener.
"They've paid a heavy price and we're expecting always to come here and to face the fire and we're ready for that."
Smith's return to Australia duty this month in three unofficial World Cup warm-up matches at home to a New Zealand XI included 89* and 91*.
By contrast, Warner could only manage a top score of 39.
"I watched Steve Smith batting against New Zealand, he's literally a master of the game, so it's nice to have him back," he said.
"He's just shadow batting the whole time...He loves batting, he's shadow batting on the sand, he's shadow batting in the shower –- I'm not joking!"
As for Warner, Langer added: "Dave's got that look on his eye, he's really hungry, he's a great player as we all know, he's so dynamic, he brings so much energy, and that's what we ask from our players."
