PSG chief Claude Makelele insists Mamadou Sakho is not for sale.
But Makelele insists: "Mamadou is the future of the club. It is impossible for him to leave. Sometimes I also had bad thoughts as a player and you have to know how to avoid them.
"Of course you want to know that you're important, but sometimes you have to remain silent.
"Mamadou has reached a level when he cannot act like a child and ask for affection. He is a professional."
