"We are learning our lessons in the Euroleague and now we know that every game in this competition demands maximum concentration and effort. It's nothing like our local league, where we play too relaxed sometimes. Regardless of who we are playing, we must turn up our defense in every game. I think defense will be a key factor in the game against Barca. We played good defense in the last game against Napoli, but we can do even better. And we will need to against Barcelona. I watched them playing a few preseason games and they didn't play very well then. But they improved their game a lot and are playing much better now. They do not put a lot on any particular player, so you cannot go after just one. Of course, the core of every team is the playmaker. If he struggles, the team struggles too, so our luck in the upcoming game depends heavily on how we handle Lakovic and Navarro."
