First disclaimer I am American. Call me bias if you want and with the links to Dike (how I think could become a solid EPL player but I dont think Everton would be the best place for him).
I do think that the talent coming out of the US Academies and the MLS is really getting to be quite good and the American market is somewhere you can get good value. The player I would like Everton to look at is Brendan Aaronson. He is an attacking winger with good pace and he is very confident with the ball at his feet. He is young and has shown at the Union and at RB Leipzig he can contribute with assists and goals. There is certainly still risk with him as he hasn't played at the level of the PL but I think Everton need to start taking more smaller risks with high upside. Only way we can get star players.
Plus if Aaronson becomes a star then you get the American market.
