Jose Mourinho and Sami Khedira have gone back over Real Madrid’s derby defeat against Atletico in detail, reviewing the match three times to identify what went wrong, reports Defensa Central ,

Notably, the derby was arguably Real Madrid’s worst performance of the season so far, prompting Mourinho and his assistant to conduct a detailed review of the game.

Their focus has centred on three problems: defensive lapses, a lack of intensity and Real Madrid’s struggles to maintain possession.

The coaching staff believe those weaknesses must be corrected now that there is an important month ahead .

The defensive issues have received particular attention from Mourinho and Khedira.

One sequence that stood out came during Atletico Madrid’s second goal.

As such, Giuliano Simeone was able to get past Marc Cucurella before delivering a cross into the area, with Antonio Rudiger moving across to deal with the danger.

The problem came with the movement inside the penalty area. Jonathan David moved into the box, while Ibrahima Konate positioned himself behind Rudiger.
