They did a four team event at RBA last summer called the Barclay's New York Challenge with Spurs, Man City, Sporting Lisbon and Red Bulls. Each team played two games - the PL clubs did not face each other. It also turned out to be Henry's debut.
Everton and Newcastle are in the area, Red Bulls are free, just need one more to make it happen again. Could even shorten it to a single doubleheader with Everton/Newcastle v. Red Bulls and the other vs. ? Would love this.
(By the way, I'm just making shit up that I hope happens)
