Except Tottenham and Arsenal, all the top clubs in the Premier League has changed owners to get that success. Liverpool were exactly where ManU are now before FSG. And Man City were worse off. Roman made Chelsea. etc.Well pretty easy fix then just look at how any top club is doing it currently and copy them, but the owners seem stubborn to want to do things their own way
Until the Glazers are gone the best they can do is paper over the cracks.
