I just think saying Mitrovic is in form and scoring therefore letting him go was a mistake (which appears to be the crux of your argument, unless I've missed something) is a simplification of a situation which most other people on here seemed to have grasped is a lot more nuanced than that.
As for the irrational obsession you're claiming, prior to this I can't actually remember the last time I disagreed with you about something on here. I did a quick search and nothing came up. No doubt we'll have had some disagreements but I couldn't find anything in recent months. Which is pretty much what I would have expected because we have very little in common and, consequently, most of what you post is of no interest to me.
