The stakes could not be higher for this early-season clásico as the league's only remaining unbeaten records are on the line. Barca coach Roger Grimau will be approaching his first meeting with Real in confident mood after his team's 39-point thrashing of Bayern last week with an exceptional all-round performance. Jabari Parker is another clásico debutant and could be an x-factor after improving for his new team game by game, pairing 15 points with 6 rebounds in Round 4. It's a special night for Willy Hernangomez as he returns to face his former team. His battle alongside in-form Jan Vesely against Madrid giants Walter Tavares and Vincent Poirier could be crucial – not to mention spectacular.
Pre-game quotes: Real Madrid vs. Barcelona

Chus Mateo, Real Madrid head coach
"A Real Madrid vs. FC Barcelona is always a different game. A Clásico is attractive because of the rivalry between both clubs and it is a special game in a season with many games. It's the third time we face them already this year and there will be more. I always expect the best possible opponent. Barcelona is showing a great level, they took a giant step forward and I cannot think about anything else than a great Barca playing against us. The only think I want is that, at the end, Real Madrid is better than Barcelona, even if they play great. We will need a good mentality, to stay focused and be patient. Another key will be securing the defensive boards and avoid turnovers."
Roger Grimau, FC Barcelona head coach
"It's always special to face Real Madrid. We give great importance to this game, but we must also remember it's just Round 5 of the EuroLeague. I think we are a better team than the last time we played there. I am happy with the evolution of my team, both on offense and defense. We want to win all games thios season and, of course, also this one against Real, and I am sure they are also eager to beat us. It's no mystery: winning this game gives you joy and losing it ruins your day."
Mario Hezonja, Real Madrid player
"We will play a very important game, another Clásico. Barcelona is playing really well but we must focus on ourselves. We must prepare well and pay attention to details in order to win. Teams change and improve throughout the season, so whatever has happened before does not count. We will need maximum concentration during 40 minutes, control the glass and try to play our best ball. Our fans help a lot, and I hope they support us as they always do."
Dario Brizuela, FC Barcelona player
"Real Madrid is not just Facu Campazzo. We have not prepared anything special for him. We have focused more on ourselves, in the things we have to improve. The games against Real Madrid have to be prepared like you are facing a whole, because they have many talented players. We go to Madrid with a good feeling, we come from a string of wins. You are always motivated against Real, whether you play in Barcelona or in Estudiantes [like I used to]. We needed a bit of time to gel as a team, and now I think this new game against Real gets us in a better moment."
