Donovan impressed for Everton during a three-month loan spell last season.
Everton boss David Moyes is keen to seal a permanent deal for the 28-year-old this summer.
An insider at Goodison told News of the World: “The manager was really impressed with Landon and tried to keep him at the club.
“There’s always a chance of him coming back but it’s a question of what LA Galaxy want.”
