Everton boss Moyes: We can't buy LA Galaxy's Donovan outright
Moyes admits that it would only be a potential loan move again, despite the fact he should have money to spend when the transfer market re-opens in January.
"It's unrealistic to sign him on a permanent deal," he said.
"We've not really invested in centre-forwards for probably three years and it has caught up on us.
"The boys we have brought in are free transfers or for very little money."
