Refrees are at each other's throat and it's glorious:
Apparently this all started when some ZDF (public broadcaster) reporter was trying to do an interview with Deniz Aytekin, who had just refereed Bayern's game. For English speakers: the Tweet is leaving out a couple of "shits".
Here we have Patrick Ittrich, also an active referee, saying he 100% understands Aytekin's outburst:
And here's Gräfe himself responding with a little "blog post":
While Gräfe may or may not have a personal motive behind his criticism (being forced to retire due to age, despite being the league's most respected ref at the time), I do think most of his observations seem on point regarding the institutional issues. Because it's an absolute joke that, despite all the money involved, there is no discernible standard of rule interpretation or VAR threshold. We have to look no further than yesterday: a little shirt pulling got a crucial goal annulled for Hertha (it was perfectly okay to do so, but I think there's been plenty of situations like this where VAR stayed out of it), while in Hoffenheim something that was in my opinion a fairly clean tackle was actually VAR'd into a penalty. So you'd think "okay, they will just VAR everything, good to know", but then you see Schalke:Frankfurt and suddenly the refs are quite generous for Frankfurt's equalizer and it's apparently okay again to slide into your opponent without getting the ball.
And it seems like, Gräfe aside, no one actually has any intention of bringing this up, let alone improve the situation. All you get is maybe a "sorry about that, but now we need to talk about the death threats that some kids sent from their mom's basement instead".
