Atletico convince Juve to extend Tiago loan
"It has been a little difficult because the negotiations weren't easy," Tiago, who spent the second half of last season on loan at the Calderon, told a news conference in Madrid on Tuesday.
"Juve wanted to sell me and Atletico wanted to buy. In the end Atletico and me are happy, Juve somewhat less."
The 29-year-old playmaker, who was cup-tied for Atletico's successful Europa League campaign last year, said it was unlikely he would be ready for next Friday's European Super Cup clash with Inter Milan.
