No World Cup-winning team has ever won the World Cup with a foreign coach in charge. Every single World Cup-winning manager has been a native of the country that won the World Cup.
So, if we want to win the World Cup, we must hire an American.
And I'm on record as saying that we'll definitely hire an Englishman considering the man in charge of the hiring process is English and he just hired an Englishwoman to run the USWNT.
