Sergio Ramos has insisted that Real Madrid must improve following their poor start to the La Liga season.
Los Blancos coach Jose Mourinho was fiercely critical of his side after they slumped to their second defeat of the campaign against Sevilla on Saturday night.
"It's rare that after four games the boss has been so tough and the team have not raised themselves," said Ramos.
"The moment has arrived for us to look at ourselves and say we can give more, that we should improve and change our attitude."
The loss has left Madrid eight points behind La Liga leaders and bitter rivals Barcelona after four games.
