#3. Aggressive use of wing backs
Should Conte play a back three, he’ll likely deploy his wing-backs very aggressively.
A prominent feature of his Chelsea side was the high positioning of Victor Moses and Marcos Alonso on either flank. Moses, a converted winger, would look to dribble at players, while Alonso sought to make late runs into the penalty area to get on the end of crosses.
It so happens that Madrid’s best performer at the moment is Marcelo. The Brazilian has played well despite the team’s poor performances.
However, in giving Marcelo the licence to go forward and do what he does best, Lopetegui has left his side vulnerable down the left flank.
In Conte’s back three system, this might not be as much of an issue. Marcelo would be allowed to play as he likes, while there’d be a better defensive cover.
On the other side, Conte would have Alvaro Odriozola and Dani Carvajal to choose from. Beyond them, Lucas Vazquez has been deployed at right-back before and could fit in nicely as a wing-back.
