Reports claim Juventus are keen to bring in Hummels after the club failed to sign Bruno Alves from Zenit St Petersburg in the summer.
“I am honored by Juve’s interest in my services,” Hummels told Tuttosport.
“To know that a club this important want me is very exciting and forces me to ask myself some questions.
“I see myself playing abroad, but at the moment I am only focused on Dortmund. Who would not like to play for Juve?”
