Take a look at who retired England hooker Dylan Hartley has picked his toughest opponents from his stellar rugby career.
#1. Richie McCaw (New Zealand)
Lifting the 2011 World Cup in his backyard was a fitting tribute to one of the greatest ever All Blacks, but he went on to secure true legendary status as he continued for four more years, breaking record after record and uniquely hoisting the Webb Ellis trophy for a second time.
Hartley wrote in autobiography ‘The Hurt’: “I punctured my lung tackling Richie McCaw during my fifteenth England appearance against the All Blacks. I hit him hard and low but came off a lot worse. He never gave an inch.”
