The Welshman was first spotted putting his mask over his eyes and pretending to sleep in the win over Granada last weekend, after finding out he would be an unused substitute.
Bale then made the headlines a few days later when he used his hands as make-shift binoculars on the bench during the win over Deportivo Alaves.
The 30-year-old's former Tottenham Hotspur teammate, Dimitar Berbatov, was less than impressed with the Welshman's antics these past few days.
"When I saw it, I couldn't believe it. I watched him put his mask over his eyes and pretend to be asleep. I cannot support that.
"It is unprofessional and disrespectful to Real Madrid. I love watching Bale play and I can feel his pain at not playing because I have been in the same situation. But that kind of reaction is going too far.
"Madrid need to find a solution to the Bale saga. It's not good for Bale or the team and it is bad publicity.
"I do feel his pain, I have been in his shoes of not playing and nobody is probably giving him any answers, then you are provoked to do those kinds of things, but I cannot support what he did.
"The only solution is for Bale to leave Real Madrid. If I was a Real Madrid fan and saw a player disrespecting the team like that, it would be too much.
"Bale should be asking for a solution, even if it is a loan move. It was a show of power, it was if he was saying: 'Play me or I'll do whatever I want.' That doesn't sit right with me."
