And he showed his knee problems are a thing of the past by leading his side to a third win on the trot - and taking another step towards the dream of scoring a 'Perfect 10' on the 125th anniversary tour.
"It's just a goal to go through the tour unbeaten. It may sound arrogant, but you have to aim high and it takes no more energy to have a big goal than a small one," said Warburton.
"It's a challenge that was first put to me by Andy Irvine on the night we met up before the team announcement. Being very ambitious I liked the sound of it.
"It's always going to be massively tough. I've found that out the hard way by playing against Australia so many times without success.
"But I'm extremely confident with the squad we have this time round. There is so much class there I think it is definitely achievable."
Willie John McBride's team won 21 of their 22 games in South Africa 37 years ago and drew their final game, the fourth Test. The teams that went to Argentina in 1936, 1927 and 1910 all ended up with 100% records, as did Bill Maclagan's side of 1891, who won all 20 matches in South Africa.
The first and foremost task for Warburton and his players is to become the first Lions side to win a Test series since Martin Johnson's team in South Africa in 1997, but the prospect of going through the whole 10 match tour undefeated is obviously appealing to the Class of 2013.
"Physically it was a good game to get used to the tempo and we would rather it happened here than happen in the first Test. It reminded me very much of the first game we played out here with Wales last summer," said Warburton..
"The first Test was a really tough game played at a high tempo and we adapted from that very well. We will benefit from this game hugely and I thought a lot of the aspects of the game went well for us - I thought it was a pretty well rounded performance.
"I hadn't played for seven weeks before this so I was pleased I came through the 75 minutes. It is always a bonus to come through injury free and the medics have done a fantastic my job with my knee. Yesterday in the team run I even forget to get it strapped."
