#4 The counter-attacking game
Zidane is known for his attacking game style. He likes his players to continuously counterattack, and asks them to repeatedly give crosses into the box.
The Chelsea board sacked Antonio Conte to appoint Sarri, but this turned out to be a counterproductive decision as the tactics of both of the Italian coaches are opposite, making it really hard for the players. They do not look too comfortable with the ball like Manchester City or Barcelona.
Bringing in Zidane will surely help the team, as he encourages more direct attacking play than passing the ball and keeping possession. With the likes of Eden Hazard, Willian and Pedro who are among the world's fastest players, the counter-attacking style will suit the team more.
Some of Zidane's tactics used in the two major finals for Real Madrid are explained below:
Marcelo and Carvajal were free to provide the width in their role somewhere between full-back and winger, while Casemiro was able to cover behind them to help the defense which now contained the extra pace of Raphael Varane alongside Ramos. Both of them gave crosses into the box where Ronaldo and Benzema stood tall and scored headers and tap-ins.
