USA manager Jurgen Klinsmann has urged LA Galaxy attacker Landon Donovan to return to Europe on-loan.
Donovan has been linked with Everton for a third spell, though Fulham and West Ham United are also keen.
Klinsmann said: "If you get a chance to go on loan to Europe, do it. It is very crucial for us that the players understand that everything they do now today has an influence on Brazil 2014 next summer. They can't take it easy.
"I always said if Landon decides to stay at the Galaxy and not challenge himself in Europe, that is his decision, but at the same time, it's my job to tell them what the next level is or could be and challenge them to get there because that is what sports is all about, measuring yourself against the best.
"Because the guys we are going to meet in Brazil 2014 are the best in the world, and I need to prepare them for that."
