You're trying to make yourself look clever because Mignolet has made mistake after mistake. Not to mention poor general play such as his kicking, ability to control a ball and pass it and his ability to command his box and calm players around him.
He's gotten away with it lightly this season due to our superb attacking play, but he is not and never will be the answer. Had he had the same season and our attack hadn't been able to score two's threes and fours in almost every game we'd have been up sh*t creek.
As I said in another thread, we've conceded more than Palace and Hull... He's a major reason for that. I would go as far as to say that well over half of the goals we've conceded this season have been down to individual errors and poor decisions made by players in defence. Very few have been directly down to the shape of the team.
With regards to Suarez its understandable you can't see his importance. Generally people don't understand intelligent play, correct decision making, vision, off the ball movement and influence. People often don't see the big picture. Luckily for us, we have a player that see's everything, scores a bucket full and sets nearly everything else up. In terms of importance, he's irreplacable. The same can't be said for any other player in the squad. Even Coutinho, Sterling and Gerrard.
