If the current substitute players cannot fulfill their expectations, the defense line will improve. So there is no harm in buying quality defenders in the mid-season transfer market. Because we know Eder Militao and Daniel Carvajal will actually be absent until the end of this season. And of course Real Madrid must look for players who are equal or close to the players who are absent due to injury. The defensive crisis experienced by Real Madrid this time is truly the worst in recent seasons. So it is not surprising that they will start to have difficulty winning matches if their back line weakens.
The winning ratio of Real Madrid have reduced rapidly and this is not the expectation from the best club in the world of football. Real Madrid in shaky position currently following the massive list of injured players, terrible for the club. Eder Militao is constantly known to be ruled out due to injury and this is no good news for the club. They've suffered huge injury blow this season and it's complicating real matters for Carlo Ancelotti who's looking forward to apprehend solid strategy for the club. However in January transfer window, this is an opportunity for Carlo Ancelotti to recruit new players because there's very tendency for the club to bounce back to limelight this season.
