Real host Napoli on Wednesday night.
"They're a very good team, not only in midfield. We'll have to fight in defence, in the middle and in attack. It is important to start the match well, to go out strongly and play well. Hopefully we'll play well and get a good result," said Modric.
"Napoli are a very tough team to beat and they're on a good run, they're playing very well, but we're at home. We want to go in to the game very strongly from the start and show that we're in good shape and we want to go out to win. We've won the last two games and we go in to this tie in good form. We are ready to do well and get a good result."
