One of the most beautiful positive news in Real Madrid this period is Ferland Mendy's return to the team's training on a regular basis.
His return to playing at left-back will be very useful for the fragile defensive situation that Ancelotti has not found a solution to since the beginning of the season.
Mendy may not be the best offensively, but Certainly his speed and understanding of his defensive duties, whether on the edge or in depth, will reduce the spaces that opponents find at every counterattack.
If he returns, I think that the quadruple Mendy Alaba Militao Lucas (until Carvajal's return) is the best to enter the next Clasico and before that, Shakhtar will face Shakhtar in the Champions League.
