Madrid came up against Leganes with a rested squad as we can see that for now Valverde, Vini and Rodrygo were placed in the reserves and Ancelotti tried out a young squad where Arda and Brahim were left free to line up in attacking midfield.

The first 35 minutes saw Madrid take the lead but it only lasted 1 minute as the penalty that was converted into a goal was immediately countered 1 minute later through an unexpected attack.
Madrid will need to secure the 3 points in this match because after all, with Atletico now slowly disappearing from the race for the trophy, Madrid are the only chance to snatch it from Barcelona now that they are still quite comfortable with their 3-point gap.
Their dominance with some substitutes is still quite good so far, it's just that it looks like Ancelotti will have to try more if he really wants to get 3 points, even so I am quite sure that they are still able to get 3 points in this match.
