Llorente could see action against Juve tonight in their Champions League clash at Wembley.
Jesus Llorente told TMW: "You never know ... In the past there have been several market rumours, but one thing is certain: in Italy Llorente would only come back for Juventus.
"He has many memories, beautiful and exciting, when you experience Juventus in Italy and in Europe you realize that it is more than just a football team, it is a historic club, a heavyweight jersey, one of the five big names in the world in this moment."
He added: "Fernando has a great desire to help Tottenham to reach the next round, even if he has great respect for Juventus and its fans."
