Alberto Contador says the Vuelta a Espana is Nairo Quintana's to lose as riders prepare for the final five stages.
Movistar rider Quintana holds a lead of three minutes and 37 seconds over Team Sky's Chris Froome, while Tinkoff man Contador is a further 25 seconds back.
Quintana has had a grip on the red jersey since winning stage 10, and Contador is not hopeful of catching the Colombian when the action resumes after Tuesday's rest day.
"Unless Quintana has a bad day, he is the winner of La Vuelta," Contador told Spanish radio station Cadena Ser.
Quintana, meanwhile, credits Contador with playing a significant role in his development as a rider.
"I've had to learn a lot very quickly from figures like Contador," Quintana told Marca.
"I followed his movements during an epic stage of his at Fuente De [four years ago] and I said to myself that if I wanted to be someone important in cycling, I would have to learn what a rider like Contador did.
"There is still some way to go."
