Zidane recently revealed the Spanish club are trying to shift the winger as soon as possible, sparking a feud with the Welshman’s agent Jonathan Barnett.
The Frenchman said he wanted the 30-year-old to leave ‘soon’ because it would be ‘a good thing for the club’.
Barnett hit back with some strong words, saying: “Zidane is a disgrace. He shows no respect for a player that has done so much for Real Madrid.”
Despite six seasons with Madrid and an incredible four Champions League titles, with the forward scoring vital goals in finals, the fans have also turned and booed him on several occasions.
Bale still has three years left to run on his £650,000-a-week contract and the sheer scale of that figure has ruled out several clubs from signing him.
