However, Donovan now insists that he hasn't closed the door permanently on a loan return.
Speaking via podcast to Everton fans website www.followtonians.com, the 28-year-old said: "I thought to myself a lot, 'If you say no, then what's going to happen next year? Are they going to let you back?'
"That was hard, because I don't want to close that door, I always want the opportunity (to go back). If I don't have the opportunity...I mean I'm an Evertonian for life now."
