Real Madrid will continue to use the 4-3-3 formation despite a 2-1 loss at home to Atlético Madrid.

"The system is not the problem," said Ancelotti. "We know it very well, we must get some players used to it. But problem was intensity and attitude."

Real Madrid has been working to incorporate James Rodríguez and Toni Kroos into their midfield with Luka Modric. The decision to sell Ángel di María and Xabi Alonso has left Real Madrid without midfielders skilled to enough play a defensive role.

"It is possible get balance using players with technical quality. Then that is what makes the difference."
