Karim Benzema struck twice in the second half following a goal from Marc Cardona, who scored with the first shot on target of the match in the 39th minute.
Benzema had two efforts ruled offside before he headed home twice in the second half to give his side the win.
But Bale was the subject of much of the frustration of the home crowd, who also booed their side off as they trailed at the break.
Zidane was coy on Bale’s future after the match. He could bring the X factor to Liverpool, remember.
He told a press conference reported by marca.com: “We will see [whether Bale will still be at the club next season].”
“Gareth is a Real Madrid player with two years left on his contract.”
The Frenchman, who has won three of his four matches since returning as manager, added: “We’re not happy about the whistles, but the public comes to see their team do well.
“There was a reaction and I’m left with that, the public knows that the season is over, that we play to try and finish second.”
Time for that swap deal with Sadio Mane?
