The Ashes 2013-14: Former captain Michael Vaughan hits back at Shane Warne over Alastair Cook criticism However Vaughan, who captained England to their first Ashes series win for 19 years in 2005, responded by describing Cook as "outstanding" and refuting Warne's claims that Australia captain Michael Clarke is the best leader in world cricket. Most of captaincy is about what we don't see...Getting the culture right behind the scenes... Cook is Outstanding in this department.. Clarke is a very good tactician.. But does he get the most important part of the job right @warne888 .. Creating the right environment?? Put George Bailey and Clarke in a blender and that would be the best Aussie Captain @warne888 .. Warne then responded, tweeting: "@MichaelVaughan Here's a question for you. If a world 11 was picked today who would Captain? @MClarke23 is the answer, best tactical Capt.
