Cummins reacted to Langer's comments on cowards in Australian team for leaking info to media.
Langer last week attacked the anonymous "cowards" who leaked against him in the lead-up to his resignation this year after widespread reports in the Australian media, citing sources, about his intense coaching style.
"There's no cowards in an Australian cricket team, not ever. I think it's disappointing sometimes the focus gets drawn to off-field issues but it hasn't really affected our team,” Cummins told reporters in Perth ahead of the first Test against the West Indies on Wednesday.
However, Langer has since backtracked on his comments and claimed he was not referring to players when he used the word "cowards".

"I think he had a think about it and clarified it, so I thank him for that. But we're really proud of the last 12 months, how we've fronted up, the way we've played, the way we've conducted ourselves. Players can certainly hold their heads high,” Cummins added.
Langer is due to commentate on the two-match West Indies series and Cummins insisted there was no "ill-will" and he was keen to catch up with him.
The Australian captain said: "I'm looking forward to seeing him. He'll be in and around here commentating, so it'll be good."
David Warner and Usman Khawaja will open the innings, with Marnus Labuschagne, Steve Smith, Travis Head, and Cameron Green as the batters, Alex Carey keeping the wickets. Nathan Lyon will be the sole spinner in the side.
The fast bowling department will see Mitchell Starc and Josh Hazlewood partnering with captain Pat Cummins.
