Germany international Sane looks set to leave City in the next transfer window, with Bayern Munich overwhelming favourites to sign him. But Yorke would love United to sign him instead to "stir it up" between the Red Devils and their city rivals.
"United has got a real good attacking bunch of young players," Yorke told Stadium Astro. "Add in Sancho, I like the boy Sane. If I was to airdrop, the boy Sane at City I really do [like].
"We haven't got a left-footed sort of winger. The boy [Mason] Greenwood is coming to the fore recently but I like Sane.
"I really do think this kid is probably the quickest out of all them as well and he's really got a good attitude.
"I know he's got some injuries but if I was brave, if I was Man United manager at this point in time that's the type of person I would go for."
