Although Flintoff has the makings of a great leader, he will still need all the support of his senior players if England are to retain the Ashes, Strauss said.
"The England captaincy is not an easy job. Any touring side to Australia realises that this is probably as tough a tour as you get," he told reporters in Sydney.
