So now we know who the mystery "Dest" is who has been recently playing for US U-17. It's Sergino "Serginho" Dest, a '00 right back and right winger with Ajax U-17. Transfermarkt says he was born in Almere, so he may be American through parentage. He has a previous call-up to Oranje U-15 and was previously with Almere City's academy.
