Alberto Contador is aiming to make up for Tour de France disappointment by winning the Vuelta a Espana, as he prepares to sign off on his Tinkoff career.
Contador, the 2007 and 2009 Tour winner, was stripped of his 2010 yellow jersey due to a doping offence.
A fever forced him to retire from this year's event in the ninth stage, leaving the 33-year-old determined to challenge on home soil when the third and final Grand Tour of the year begins on Saturday.
It will also be his last major race for the Tinkoff team, which will cease to compete in the sport at the end of this season.
"Certainly, my goal at the Vuelta is to fight for victory," Contador told the team website.
"That's the idea with which I am going to Galicia, we will then see if we can achieve it, because I will have to face very strong opponents with powerful squads.
"We will have to take it day by day and I just hope I'm a little bit luckier to enjoy the race and the fans. At the Vuelta, the affection of the public has always been amazing and reliving that is something I look forward to.
"Furthermore, this will be my last Grand Tour with Tinkoff and I would like to finish it in the best way."
Contador insisted his goal of succeeding at the Vuelta, which will also be contested by Tour winner Chris Froome of Sky, is not motivated by a desire to get one over his rivals.
"No, it's not a matter of revenge, the Vuelta is another race that starts from scratch and I just hope to start on a better footing than the Tour," he said.
"The level is very high, because in the end, each year the favourites of the Tour are in the Vuelta and that makes me happy. This marquee line-up will raise great expectations."
