We got Sean Johnson out at LAX ... a goalkeeper for the Chicago Fire of the MLS and a member of team USA ... and asked him about Will joining the ownership group of the new soccer franchise in L.A.
Check out the clip -- Johnson is obviously stoked about Ferrell ... saying big stars like Will and Seattle Sounders owner Drew Carey are just the type of high-profile attention the league needs.
Just make sure to have some juice boxes handy, guys.
