Not precious but i think it's ridiculous to suggest they wouldn't know who we were prior to 2008. They might not know the clubs entire history but they'll certainly be aware we exist. They're professional footballers, their entire life is football and always has been, i'm confident the vast majority of footballers when growing up would have been well aware of every premier league team and a few more in England. Back when we were shit we were probably best known for being Uniteds closest rivals than anything else so there's probably a lot of people that grew up knowing us purely as that but they still knew of us.
