Further doubt is cast over Bale's future after he snubs Real fans
Unused substitute Gareth Bale walked off without acknowledging the home support after Real Madrid's final La Liga match this season ended in a dismal 2-0 defeat by Real Betis.
Speculation over the future of the 29-year-old, who joined for a club record £85m in 2013, has intensified this season with reports suggesting he is set to leave.
Zinedine Zidane, who returned to the club in March to become Real's third coach of the season, would not be drawn on the Welshman's future.
The manager said: "I don't know what will happen. I've called upon other players lately. I'm making decisions about who plays and who is on the bench, but next year anything can happen.
"Today he didn't play because others have come in. I'm sorry he didn't get minutes, but next year who knows what will happen?
"I have to take decisions and when I don't like things or something doesn't seem right, I have to change them.
"Nobody is going to change what the player has done at this club, but day-to-day, it is like that. We live in the present, although we will not forget the past."
Despite not being in charge for the majority of the campaign, Zidane has accepted his share of the blame for Real's disastrous season.
"What happened this year has to be accepted. I'm to blame - we've had 11 games and won just five. That is what it is," he said.
"We have to focus on next season because we want to please the fans and I can tell them that we are going to prepare well in pre-season. We are going to have time to focus on our work and set up a great season. We're going to compete from the off."
