#4 Improvement in their build up play from the back
The key to the success of Barcelona in the league over the years is their build up play from the back, and the involvement of their full-backs in the attack - with Jordi Alba and Sergi Roberto for example constantly making forward runs.
Last season Real Madrid struggled to build up play from the back. The new manager believes that his defenders should be able to contribute to the team attack as much as players in other positions, and should be efficient in switching the ball.
With Lopetegui at the helm, he likes his defenders and midfielders to work as team, Real will be creating attacks from the back with their full backs higher up the pitch.
The likes of Marcelo and Dani Carvajal certainly possess the attributes Lopetegui wants in his defenders.
