The American international, who has 138-caps for his country, impressed during two previous stints on Merseyside during the MLS close season with the most recent ending in February.
Before he departed back to Los Angeles the 30-year-old confessed that he was unsure as to whether he’d be back Goodison Park as a player or fan but would return in either capacity.
He said: “I would absolutely like to come back. There’s no question about that and I know I will be back at some point.
“Now, whether I’m back as a player or just as a fan, who knows?
“I’ve always said the same thing: I’ll see how my body feels, I’ll see how I feel mentally, I’ll see where the Galaxy are at and what they’re okay or not okay with and then we’ll make a decision.
“Obviously a big part of it too is whether David Moyes wants me.
Donovan acknowledged there were numerous stipulations that would need to fall into order for him to pull on a Toffees shirt next season and is refusing to get his hopes up over the matter.
“There are a lot of factors that go into it.” The striker said. “I don’t see it as a foregone conclusion that one: I’ll be physically okay to go, two: the Galaxy would let me go, and three: that Everton would want me.
“You have to make sure all of those aligned and if it all works out, then it works out and if not, then it doesn’t.”
It’s unclear whether Everton boss David Moyes is chasing the American again with speculation linking him with a move for Michael Owen following his release from Manchester United.
