Donovan says he'd welcome a return to Goodison Park for a third time.
"I miss the people. I miss the people a lot," he told evertonfc.com. "I miss driving to Goodison Park. I miss just the positive energy of the fans walking into the stadium and how much they care about that club and the team. And I miss the players a lot.
"The players are really what made it easiest for me when I first went. I'll be forever indebted because with a lot of teams' guys there would be jealousy, they wouldn't be welcoming, and they would do everything they can to not allow you to get on the field in that couple of months. It was the opposite when I first got to Everton and I will always remember that."
