N'Diaye simply rates the Belgian ahead of Arsenal goalkeeper Wojciech Szczesny.
He said: "I can understand why he has been linked with other teams because this is normal. It is very normal for that to happen when you play as well as he does.
"He is better than the keeper at Arsenal, Szczesny, he is better than him - no doubt about it.
"Mignolet was brilliant against Southampton and he is like that every week. He is such a good keeper and that is why he is being linked with other clubs."
