Warren Gatland has made 5 changes for the second test against Australia this Saturday in Melbourne with the big on in the backs at scrum half where Ben Youngs replaces Mike Philips who is dropped from the match day 23.
Tommy Bowe comes in on the wing having made a miracle recovery from a broken bone in his hand meaning Alex Cuthbert is on the bench.
Vunipola replaces Corbisiero in the front row and starts beside Tom Youngs and Adam Jones
Alun Wun Jones and Geoff Parling are the second row , Parling replaces Paul O’Connell.
Lydiate, Warburton and Heaslip form the back row, Tom Croft loses out.
To asses the Wallaby and Lions starting teams I spoke to former Leinster, Ulster and Scotland coach Matt Williams who’s following the tour around his home country and who days the Australians backline looks better set up for this weekends match.
