The former Tottenham midfielder played the full 90 minutes of the 1-0 defeat to Rayo Vallecano on Sunday, but Zidane wondered whether the player’s heart was in the right place.
“I don’t know if Bale is focused, you’ll have to ask him,” the Real Madrid boss said.
There has been continued speculation regarding Bale’s future at the Bernabeu over the past couple of seasons, despite him having a current deal with the club until the summer of 2022.
