No, the Seattle Sounders are not at the top of the list of most expensive transfer fees paid. That honor lies with Atlanta United FC and teen phenom Ezequiel Barco. The rest of the top five are players that have performed at high levels in MLS — Miguel Almiron, Michael Bradley, Jermain Defoe and Clint Dempsey (Dempsey’s fee was paid, at least in part, by the league).
But that’s the entire list of larger transfer fees paid than the one for Raúl Ruidíaz to come to Major League Soccer, as collected by Transfermarkt and converted to US dollars.
