Downs earned his first caps with the USMNT this summer, featuring in the June international window and during the CONCACAF Gold Cup. He made five appearances for the U.S. across both windows, cap-tying him to the United States after being a dual-national with both Germany and the USA.
After the Gold Cup, he secured his transfer to England, following a breakout season in the 2. Bundesliga season with Köln, where he led the team in scoring and helped secure their promotion to the German top flight.
With Southampton, he'll be pushing for a spot in the USMNT's September roster under manager Mauricio Pochettino.
