Toni Kroos is playing one of his worst seasons since he became an elite player. His contribution to Real Madrid this year has been disappointing and he even stayed on the bench during Real's 1-0 loss to Villarreal, a game in which Benítez thought Casemiro was more useful. Kroos wasn't happy with Rafa Benítez and his system, so he considered leaving the club to join either Chelsea, Manchester United or PSG, but that has changed now that Zidane has taken over Madrid, according to OK Diario.
Something was clearly wrong with Kroos. The midfielder completed a brilliant season under Carlo Ancelotti last year, so he managed to adapt to Spanish football quite successfully. However, Benítez's change to a 4-2-3-1 formation did not help his game as he was too isolated to dismantle the opposition's counterattacks. Zidane wants every player to help on defense and that's why Kroos was much more comfortable during Real's 5-0 win to Deportivo.
It will be interesting to see if Zidane's plan translates to matches against elite opposition, but for the moment it seems that Kroos is a much happier player with Zidane holding the reins.
