Richie Porte has set his sights on leading Team Sky in one of next season's Grand Tours after signing a new deal.
The Australian was a key member of the Sky line-up that delivered a Sir Bradley Wiggins-Chris Froome one-two at last year's Tour de France.
Porte will again play a supporting role to Froome this year, but is keen to emerge from his team-mates' shadows in the future.
The details of the new deal have not been released, but he said: "With this new contract comes an added responsibility.
"While I'm more than happy to help guys like Chris Froome and Sir Bradley Wiggins in the future, I would love to lead the squad in a Grand Tour next season."
Team Sky boss Sir Dave Brailsford said: "Richie has been a key part this team's stage-race success since he arrived here and this new contract is a statement of intent for both him and the team.
"Every time he has taken on a leadership role he has excelled. We saw at Paris-Nice exactly what Richie is capable of and there is no doubt that there is a lot more to come from him.
"If he maintains his current trajectory there is no reason why he can't go into a Grand Tour and challenge for victory."
Porte has enjoyed his best start to a season in 2013, capturing victory at Paris-Nice in March and two second places, at the Criterium International and Vuelta al Pais Vasco.
Porte joined Team Sky at the start of the 2012 season and played a key part in Sir Bradley Wiggins's historic success at last summer's Tour de France.
The 28-year-old possesses the ability to climb and time trial with the best riders in the world, making him a prime candidate for leadership in future Grand Tours.
