Christian Karembeu says Real Madrid have lost focus on the pitch.
The former France international won two titles at Real and remains close to president Florentino Perez.
"In the matter of business, they know what to do. But in terms of sport they lack many things," he said.
On Barcelona, Karembeu said: "Pep Guardiola has led an exceptional season. I can only applaud and congratulate him."
