I wonder if there will be any events where the winning marks will be better than at the U23 european championships ...? Sadly some big names (Ingebrigtsen, Burgin) are missing, but there are still more than enough very promising talents left (Kokhan, Lillefosse, Vicente, Seedo, Nacheva, Van Klinken, Miller, Sclabas, Mahuchikh, Tzenggo, Healy, Hunt, Scotti, Van de Velde, Bol, Carmoy, Iapichino, Johansson, Sotero, Ivanenko, Sorgeloos).
I think out of the smaller nations Switzerland, the Netherlands, Ireland, Greece, Spain, Belgium and Belarus should do really great.
Interesting note: In the men's discus throw there will be twins from the Czech Republic competing who could both win a medal. Also Belgium and Belarus seem to have tons of medal contenders across many disciplines, those nations seem to do a great work at junior level.
