Just based on the previous appointments as well as gut instinct of what UEFA have done or might do, I think the following will all go as referees:
I think most of the elite group will be picked so quite a lot of countries will have two refs.
So that will be:
Both Taylor and Oliver
Brych & zwayer from Germany
Lahoz & cerro Grande from Spain
Cakir from turkey
Hategan from Romania
Skomina from Slovenia
Dutch couple Kuipers & Makkelie
Orsato for Italy
Marciniak from Poland
Soares Dias from Portugal
Grinfeeld from Israel
And Turpin from France
I think Frappart will be picked as a political decision rather than a sporting one. Last chance for Zwayer before Steiler is favourited. The rest of the elite group will go as 4ths
I can't disagree with most of the names of your list. But IMO Stieler has a big chance of attending (remember he did a CL R16 and Zwayer only EL). Moreover Skomina is injured and I don't think that he will be ready until then. Vincic is a good alternative (he did a CL R16 debut).
Thanks Edy. Shame about skomina as he is in top 4 refs in europe for me
