Mignolet produced another uncertain display in Liverpool's thrilling 3-3 draw with Arsenal on Wednesday, seemingly at fault for the first two goals let in at Anfield.
Despite Mignolet's erratic form and speculation a replacement could be signed in January, Liverpool manager Jurgen Klopp has publicly backed the Belgium international amid reports a new contract is set to be signed.
And the 27-year-old himself is secure in the knowledge he is trying his best and comfortable at the level he is playing at, regardless of the criticism levelled at him from the media and the stands.

"If you concede a goal, it can be up to seven or eight mistakes leading up to it but, obviously, as a goalkeeper you have to accept it has gone past you," Mignolet told the Guardian ahead of Sunday's clash with Manchester United.
"After that, you have to accept that the first question that will be asked, by everybody in the stadium or around the world, will be: 'Could the keeper have done better?' That's part of the job. You learn from that and there is no point worrying about that.
"The only way is to be your own biggest critic, always looking at yourself and, after every goal, standing in front of the mirror and asking: 'Well, could you?'
"If you are objective enough to say: 'I could have done this, this and that's, all the other critics and all the other voices are really not important and don't exist anymore."
"Every time you concede a goal, you don't have to put a hammer to your head.
"Nobody's perfect and nobody is without mistakes. The only thing you have to make sure of is you keep improving."
