Real Madrid wing-back Marcelo says they must not relax after victory over Real Betis.
Real remain ten points clear at the top of the table.
"We knew it would be tough, but we had to concentrate because they could always score. We had to be ready. Betis are very good at their stadium," said Marcelo.
"We have a 10-point cushion, but the league isn't over yet and we must continue fighting to the end."
