I think each case should be taken individually, I've seen people use the Valencia comparison before and the one where Gibson will come good here because Fletcher did but I find that similar to whole "He's the new Messi" type of thing that goes with every half talented Argie kid that pops up..
Obviously every case should be taken individually but the point stands that if Fergie rates a player that player has a good chance of being a success, whether or not the great and good on redcafe are excited about the purchase.
In fact, when you think about it, it's the high-profile signings that cause the least excitement amongst transfer muppets that have tended to be the most unequivocal success stories.
