There's no point arguing it mate. You're right but there's no point. Both players could've done better but people just have their biases and will excuse or blame a player based on those rather than the actual incident.
For me it's not about blame - it's about assessing a players abilities, decisions, skillsets and how they deal with problems.
If Mignolet is slow off his line, poor using his feet to deal with problems, reckless in challenging, slow to react - or whatever is being thrown at him, it doesn't really matter that Matip fucked up needing those skillsets to be called upon - he is either effective, or not, in dealing with problems using them. Because in our system closing big spaces quickly and challenging opponents for the ball is going to be high on the list of things the keeper needs to excel at.
For every 1-v-1 challenge our keeper makes there will be someone fucking up before that causing it to occur. But we still need a keeper good in those situations because they are going to happen. And the higher your line and larger your spacing between the defensive line, the more frequently they will occur. With us having split center backs and defending the half way line, we can expect a lot of 1-v-1. We can either be congratulating the keeper for dealing with (some of) them, or looking at which outfield to blame the goals on. I would much prefer the former.
