Major League Soccer commissioner Don Garber hopes to keep Landon Donovan in his homeland for the rest of his career, dashing Everton's hopes of signing their former loanee.
The 28-year-old forward impressed while on loan with the Toffees last season, but a permanent deal for the LA Galaxy ace looks increasingly unlikely.
Garber commented:"He's become a real football hero.
"MLS needs football heroes and we have a great American football hero playing for us in LA, holding the torch for the sport in our country and that's very important.
"I don't believe that it's something we can do without.
"Landon proved in England last year on loan and he proved in South Africa that he's a world-class player and he's also proved that he loves our league and really has accepted the mantle of really being one of the leaders of the sport.
"It is my hope and my expectation that we will have him for the rest of his career, because I think the contributions that he makes are invaluable to our future success."
