Real open their Liga defence with a derby against Atletico Madrid this weekend and Schuster insists: "There's no concerns. I am calm. Why should I be worried?

"You can't argue with five goals being conceded. Errors were made and the referee favoured the opposition.

"We're not happy, but we must continue working in training and forget what has happened. We have a very important game this weekend and there will be no psychological problems."

Asked if his team still needed strengthening, Schuster added: "Something can happen if we find a player who can improve us. Something is happening and the player will be a welcome addition."
