Spotted Flycatcher, Grauschnäpper

At least I correctly guessed it was juvenile... ;D
I think you are right, here is one juvenile of M striata - https://en.wikipedia.org/wiki/File:Juven....

Hallo Zlatan, thank you for suggestion, I'm not sure, didn't see any brown or rusty underparts...maybe this can be Muscicapa striata?

I'm not sure here, it does look like one of thrushes (Turdidae family); and juvenile one. Seeing it, my first thought was juvenile of Rock Thrush (M. saxatilis) - however, their range does not fully fit, or this spotting would be at the extreme edges... Moreover, I can't see underparts (belly and vent) - if my suggestion was correct, there should be some rusty-coloured parts on vent...
