Ferguson, easily for me. Both dominant domestically, but one in Europe looked like an elite player, and one was a liability in the majority of his European games for us.
Having all the talent in the world doesn't mean much when you can't use it when it was needed most.
Gazza was a better player but looking back it was great seeing a young Scottish boy who'd came through our youths leading a team of fantastic players and still standing out. Loved watching both in a blue shirt.
Gazza was world class and gets my vote. Don't think I've seen a player smash midfield to pieces like he did.
Barry was a different era, the future when I first saw him. If we had a midfielder like Ferguson now we'd be in a better place.
