Chelsea striker Fernando Torres has refused to rule out a return to boyhood Atletico Madrid.

The £50 million (€60 million) signing for Liverpool made his Atletico debut in 2001 before leaving for England six years and over 80 La Liga goals later. 

"In football you never know. You can't be sure where you're going to be tomorrow or in a week or in 10 years," the 30-year-old Atletico canterano told Spanish sports daily AS, revealing his admiration for Colchoneros manager Diego Simeone.

Atletico's top scorer Diego Costa has been linked with a move to Chelsea this summer.
