"We are not afraid of Juventus. They are a great team that we respect, but we are not afraid of them," Modric told Madrid's official website.
"They have a great squad with great players, and when you play big matches like this you want the best players from the other team to play against you. How do I prepare for these games? Personally I want to play my best and help my team to win all of the matches and trophies possible.
"I prepare for Champions League matches in the usual way, the same as for a league match. There is not much difference between getting ready for one or the other."
Madrid currently top Group B with nine points.
