Of course Cakir won't be demoted, even though, it is said that Ceferin is angry with him. I believe that he will retire after EURO 2021 and be replaced with Palabiyik. The latter is being pushed atm and seems to have committee's trust.
Hategan writes history with his 5th (!) CL appointment. Also Makkelie with his 4th appointment. Both are considered as safe pair of hands and locks for the Euro.
Stieler with an important match. The German will be Elite soon.
I agree with TTFL about Kralovec and Sidiropoulos. They should be demoted. I would add Collum as a demotion candidate.
Thanks as always for the very informative post Edy. Indeed it will be interesting to see the changes in categories. It is a shame about Sidiropoulos, I think he had a lot of potential to be a top referee but he seems not to have reached that level, domestic matters probably don't help.
