The US' all-time leading goalscorer has netted five times on the way to the CONCACAF Gold Cup final and suggests that he is now back where he belongs after a brief hiatus from both club and country over winter.
"I'm enjoying myself," he said.
"I think it's the most relaxed I've ever felt, and the most enjoyable it's felt in a long time. When that's the case, I play well."
US teammate DaMarcus Beasley, who is skippering the side during the tournament, was not at all surprised by Donovan's swift return to the top.
"This no surprise to me. This is what Landon does," Beasley said. "He thrives in this kind of tournament, he thrives when people start doubting him.
"He doesn't worry about the media. He doesn't worry what people say. He just goes out there and plays football. That's what I applaud him for, and he's shown in this tournament that there is no doubt about [whether] he'll be on the World Cup team."
