Had a response from UK distributors (below).
"This release will be from Panini America; I’m sure we will have access to the collection at some point but we do not have any pricing on this as it stands unfortunately. I will keep you updated with any information I receive about this collection."
As and when I get any info from them I'll post on here.
Distributors seems much more informed than Panini... Ask them about the collection, they never heard of.
That sounds pretty decent, bet none here can name 1 Albanian or Icelandic player(Sigurdsson from Swansea).
Base set is 250 so some teams will have 11 players or more, some will have 10.
Oh yeah? I can't, but Google can: Cana, Berisha, Hysaj, Balaj, Xhaka, Gashi, Cikalleshi, Lenjani, Mavraj, Sadiku and so on
Honestly, I remembered one without checking: Gashi, because of his sticker in CL 2014/15

But even though Portugal played against them in the qualification, I couldn't remember more... The only thing I remember was they had a good goalkeeper, a good forward and a very good teamwork.
Iceland I remember a guy with a huge name (as usual in Iceland) from Olympiakos (again thanks to stickers and cards) and of course, Gudjonhsen from his times in Chelsea.
