In that match, Real Madrid did not field the main squad and the back row was also filled by two defenders who did not have sufficient flying hours. However, regardless of the many goals conceded by Madrid lately, it was indeed because the crisis in the back line was very severe. Of course, the victory was an important capital and became motivation for the team to return to the path of victory.
Only a few people were not fielded as starters by Ancelloti, but can that be a justification for the weakness of Real Madrid's playing pattern. Moreover, the players who benefited from Ancelloti were much better than the Leganes players themselves and Real Madrid should not have had so much difficulty. Although the back line crisis is indeed being experienced by Real Madrid due to injury factors, Ancelloti should have understood the need for victory in every match much better and was lucky enough in that match that Real Madrid managed to win the match.
