Healy was quoted as saying in a leading cricket magazine- Cricket World in an interview to ABC Sport that said Hayden needed to find some form in England or his Test career would end.
"He should be fit, he should be fresh and if he doesn't bounce back he's finished,' Healy said.
Healy said that it would be great thing for the Kangaroos if the big man is able to get back his appetite for runs.
"And that's it. It is pretty clear for Haydos right now. It is going to be quite obvious how his appetite is, he's been a little bit bored I think in the last six months of his cricket, and if he gets his appetite back he'll be sweet."
It may be noted that the openiing swashbuckler has struggled for form in Australia's past four Test series and has not scored a century in his last 12 matches.
