But Mignolet believes he is becoming a better goalkeeper at Liverpool and is paying little attention to criticism.
He told the Liverpool Echo: "I had a difficult month but you are going to get them as a football player.
"You are never going to get everything go your way and you have to accept that.
"I didn't change anything. I just tried to stay focused and do the things I'm asked to do. As a keeper I just try to help the team out whenever I can.
"It's nice to work with Luis and Daniel day in, day out as it makes you better as a keeper.
"We all know what they can do and it's unbelievable. I see that quality every day. When you are one-against-one with strikers of that quality, you learn a lot of things."
