Not many go to the Championship as the ones who transfer out tend to have their sights set on top level leagues. But some notable MLS exports in the last 5 or so years include:
- Miguel Almiron (Newcastle)
- Jhon Duran (Aston Villa)
- Ricardo Pepi (Augsburg -> PSV)
- Alphonso Davies (Bayern Munich)
- Brendan Aaronson (RB Salzburg -> Leeds)
- Tyler Adams (RB Leipzig -> Leeds -> Bournemouth)
- Taty Castellanos (Girona -> Lazio) - Daryl Dike (West Brom)
- Adam Buksa (Lens -> Antalyaspor -> Midtjylland)
- Tajon Buchanan (Brugge -> Inter Milan)
- Ismael Kone (Watford)
- Moise Bombito (Nice)
- Kevin Paredes (Wolfsburg)
- Mark McKenzie (Genk)
- Alistair Johnston (Celtic)
- Gianluca Busio (Venezia)
- Matt Turner (Arsenal -> Forest -> Crystal Palace)
- Aiden Morris (Middlesbrough)
- Chris Richards (Crystal Palace)
- Tanner Tessman (Venezia -> Lyon)
- Auston Trusty (Arsenal -> Celtic)
- George Bello (Arminia -> LASK)
Narrowed my list to just transfers from the last 5 years.
That is why I didn't include guys like Dempsey, Donovan, or even other USMNT legends who came from MLS like Brian McBride, Tim Howard, Tim Ream, Geoff Cameron, etc...
Not really. Started his career at Leverkusen but never made an impact. Came back to the US and excelled. While with LA Galaxy, he did a series of short-term winter loan moves. First Bayern and then twice with Everton.
