#2. Sam Warburton (Wales)
He led Wales to the 2011 World Cup semi-finals, winning 74 caps for his country as well as 49 as captain.
Playing in one British and Irish Lions tour is something rugby players aim for, but Warburton became their youngest ever captain for their 2013 tour of Australia, only for the side to lose the second Test after he sustained an injury.
Under his leadership, the Lions claimed a first Test series victory for 16 years when they beat Australia, and then drew the series against reigning world champions New Zealand in 2017.
David Pocock said: “He was such a big part of the psyche of the Welsh team and their guys really looked to him for direction. He was the go-to man for the Lions too.”
