The Mexican international, formerly of Barcelona and Tottenham, is being linked with a summer shift to MLS from Spanish side Mallorca and although Donovan is unsure of any proposed transfer, he admits it would be a bonus for the reigning champions.
"I think he's a fantastic player," he said. "Certainly, he's hurt us many times with the US team.
"As far as talent goes, there's not many players I've played against that are that talented. So we'll see what happens.
"I think to this community, [bringing in a Mexican player] would be really important. It's been quite a while since this team has had a Mexican player, I think, and it would be pretty cool. But let's not put the cart before the horse."
