After Australia endured a tough day in Brisbane heat on the opening day of the ongoing second cricket Test against India, Warne singled out Starc, who went wicketless, saying: "He has to change his body language, it needs to be stronger -- he looks a bit soft.
"He needs to puff his chest out a bit, look harder," Warne said on Channel Nine during a commentary stint on Wednesday.
"Soft? He used those words? That's very harsh. I will take it up with Shane myself."
However, Warne denied calling Starc soft this morning.

"I never at any stage called Mitchell Starc soft," Warne said today.
"What I did do was say his body language and his presence gave the appearance of being nonchalant and he needed to improve on his body language, it all was a bit nice and soft and easy, not him. I stand by what I said because I agree with it," he added.
"Just to back it up, I spoke to Darren Lehmann last night. I texted Boof and said, 'mate, do we need to chat or are we good?' We spoke and he said, 'what you said is exactly what we've been saying.'," he said.
"Craig McDermott the bowling coach and Darren Lehmann have both been working on Mitchell Starc. Mitchell Johnson even said last year he had to work on his body language and have a look at how good he is - the best bowler in the world.
"That's all I meant by it and I stand by what I said.
