Real Madrid sealed their first UEFA Champions League win of the season when they beat Galatasaray 1-0 a fortnight ago, and Los Blancos host the same foe on Wednesday hoping for a repeat result.
Zinedine Zidane's side sit five points below Group A leaders Paris Saint-Germain—who host Club Brugge on Matchday 4—and are in desperate need of three points if they still hope to finish first in the pool.
Local rivals Atletico Madrid are on the road in their European return and visit Bayer Leverkusen, while joint-Group D leaders Juventus make the trip to Lokomotiv Moscow.
Premier League giants Manchester City travel to Atalanta and can seal first place in Group C if the other contenders—Dinamo Zagreb and Shakhtar Donetsk—see out the right result in Croatia.
