#3 Porous backline
Real Madrid's backline has, for all their quality, been out-of-sorts this season. Conceding goals during crucial moments in matches, they have conceded more than a goal per game and it's seriously hurting them, especially considering the fact they're struggling domestically.
Raphael Varane and in particular, Sergio Ramos, look vulnerable against quick attackers and the team appear almost lost when a dangerous counter-attack is on for their opposition.
Marcelo, for all his attacking brilliance, is quite frequently caught out of place and around 30% of goals conceded have stemmed from his flank. The ever-dependable Dani Carvajal was sidelined with a heart problem and despite Achraf Hakimi showing promise, the teenager is still too inconsistent for a regular starting spot.
In future, it appears clear that they must focus more defensively to avoid dropping points needlessly - especially when they struggle offensively against rigid opposition.
