Spurs and Juve will meet in the round of 16.
Llorente's brother, Jesus, told TMW: "For Fernando it's a very nice thing to come back to Turin, because it's like coming home, it's been three years and Fernando continues to feel affection for the fans.
"Obviously, like any professional, he wants to score for his team but I'm sure that if he does he will not celebrate scoring as happened in Sevilla.
"He's very happy, he's in a big city and a big club with a lot of aspirations.
"It was not easy at first, the injury to his arm greatly delayed his physical preparation."
