Former PSG coach Laurent Blanc can understand Zinedine Zidane resigning from Real Madrid.
Zidane quit Real just days after winning the Champions League at the end of last season.
Blanc, formerly of Barcelona, said: "It's huge what Zizou did.
"When we have lived this profession from within we can understand it. After that, you have to have the ability to do it. There are not many coaches that can do it.
"There are always things that keep you going ... but Zidane had noticed things in hand, as we saw later with Madrid."
