We can forget about doing business with Man u after the poznan, ridiculous thing to do after they loaned us wellbeck and sold us Brown etc.
I don't think the poznan antics at last season's finale will have any bearing on us loaning players to you. Having said that, Bruce or Keane were in charge when we did send players there so that will probably come into Fergie's thinking. It's probably academic anyway, since Hernandez will highly unlikely by leaving on loan, if at all. If he did leave on load I'd expect Wigan would be Fergie's preferred choice, as with Cleverley, but as some of the posters have stated he'd gain nothing from a loan, he's already United first team quality and if it's for fitness then there's no chance it would be for anything longer than 3 months.
