The impact of widespread injuries mean Real Madrid can only name eight substitutes on their bench today, including two goalkeepers.

Carlo Ancelotti can call upon out-of-form veteran Lucas Vazquez, a half-fit David Alaba, left-back Fran Garcia, then two (albeit very talented) players who have barely been trusted in the league in Arda Guler and Endrick.

Only Luka Modric, arguably, doesn’t give you a drop-off in quality among the replacements, and he enters his fifth decade in September.

Atletico, meanwhile, have World Cup winner Nahuel Molina, European Championship and Nations League winner Robin Le Normand, and big summer signing Conor Gallagher.

Plus, in attack, the useful Angel Correa and Alexander Sorloth, who is scoring roughly at a rate of one in three in all competitions. If the game is tight late on, that could prove the difference.
