The former French defender criticized Paris Saint-Germain after the intention to hire Manchester United midfielder Ander Herrera was announced last week.
Sagnol also claimed that PSG does not need a player like Herrera, having paid £ 43 million ($ 57 million) for Leandro Paredes in January
"For me, this is not the level that the PSG must aim to overcome a level. Today, the PSG must pass a course," he said. RMC.
"I keep saying today, I don't know why they paid € 50 million for Paredes. For me, it's still an enigma. Ander Hererra is no better than Paredes. He is the same type of player and they are not the ones who make you go through phases.
"If you want to be a great club and win the Champions League, you need great players. You need a general in the middle."
