Jovic is being linked with Manchester United this week. The striker played 56 minutes of Los Blancos' 1-0 win over Real Valladolid on Wednesday night but has been linked with a move away from the club before Monday's deadline.
"I can't confirm anything until October 5," Zidane said at full time.
"He's a player from this squad.
"I decide [on the team] and that's it.
"I'm not going to say anything about what's going to happen.
"Anything can happen.
"He's here and he played today."
