Real Madrid boss Zinedine Zidane insists he's not playing favourites with his sons.
Real goalkeeper Luca Zidane and midfielder Enzo Zidane are in Real's US tour squad.
“I'm the coach," said Zizou.
"They're good enough to be here and be training with us and that's all there is to it. At home they're my sons, but we're here to work and they've got just the same right to do that as the others.
"We're focused on our work."
