The Wales captain was informed on Friday that he would not be in today's squad for the clash with Real Sociedad. It will be the second consecutive game Bale will miss.
For some, it's been suggested Zidane is keeping Bale sidelined as he is one booking away from suspension and wants him free for a farewell game next week.
However, AS says Bale has had no contact with Zidane and is baffled why the Frenchman is treating him as he is.
Bale's agent was told last month the winger wasn't in Zidane's plans for next season and that he should be seeking a new club for his client.
Statistics released today show Bale has managed to play just 53 per cent of the minutes available since his 2013 move from Tottenham.
