Wales star Bale has been out since suffering ankle tendon damage that required surgery during a 2-1 win at Sporting CP in the group stage.
Speaking ahead of Saturday’s LaLiga match with bottom club Osasuna, Zidane was tentatively upbeat over the prospects of the 27-year-old forward featuring amid the typically daunting atmosphere at Stadio San Paolo next month.
“I think it’s March 7 when we play Napoli. Hopefully, it would be great news if he could be back,” Zidane said.
“He’s training but he’s yet to train with his team-mates. He’s training well and he’s looking forward to returning.”
