I don't think the team would have to have a rich backer. I may be wrong, but I'm sure Arsenal didn't have a cash injection, they have just benefitted from good scouting and shrewd deals. They used to finish around mid-table (I think?) in the mid-nineties and look at them now, they are classed as a top four team.
My heart is probably ruling my head here but I think Newcastle have the best chance in the next ten years. We've finally good a decent academy now, producing players like Taylor, Edgar, Huntingdon, Carroll etc. and the youth team is in the semi-finals of the FA Youth Cup. I think we need a manager of Bobby's ability again to make us a title challenger.
I think players like Owen will help us to attract players, regardless of his reasons for being here. As with Taylor and Milner in a few years, who will be England first teamers.
