Seems that the French boss was right when he stated that the team needed some changes to keep winning, as players that earned him three Champions League titles seem to be a bit tired. Only the last-placed in La Liga has conceded more goals than Los Blancos, as these numbers show.
Zidane decided to give a starting nod to Marcelo over Sergio Reguilón, a player that has performed his defensive duties in better fashion than the Brazilian this year.
Furthermore, Keylor Navas was blamed by some for his poor reaction that led to Valencia's opening goal.
The last nail on the coffin came when Casemiro failed to defend a corner kick. All three have been criticized for their performances in key games this season.
Maybe it's just a coincidence, or maybe Zizou should really begin to draw out some conclusions on where his team needs a tweak or two.
