Rafael Benitez held a sombre media conference after Madrid’s 10-2 win over Rayo, with the home supporters booing their team.
Madrid turned around a 2-1 deficit, to go into the break 4-2 winners with the fans still booing.
And with Bale getting four goals and Benzema three goals, Madrid finished as winners.
“There were three phases in the game,” he said. “First we scored by getting behind their defence, then we lacked intensity and conceded.
“Finally, bit by bit, we took control. We took advantage of our numerical superiority.
“We can only try and play well and score goals. We did that.
“During the game we lost concentration at times but overall the team did what they had to do, took control of the game and scored goals.
“The players scored early and the fans were happy. When we make mistakes, nobody wants that to happen, but we rectified things.”
Benitez refused to be drawn on the pre-match catcalls sent his way and also responded in vague terms to an incident where Cristiano Ronaldo – who contributed two goals to the rout – appeared to gesture towards the stands in an attempt to persuade the fans to stop whistling.
“I was late on to the pitch and focused on the start of the game,” he said. “The team looked good at the start and scored.
“As a coach you try for your team to score and want to make it hard for [the opposition] to score against you.”
On Ronaldo, Benitez added: “Players know the fans are not happy at some moments and that they [the players] have to do better. We tried to do that.”
