Missed opportunity, they should have built a proper 75K+ State of the art stadium, rather than all these Mickey Mouse lean-to's.
I prefer we stay at Anfield, building a new stadium would have saddled us with huge debts.
Staying at Anfield has its attractions for me too, but unfortunately it requires us being stuck with an outdated and uncompetitive stadium in capacity terms. Stadia of the future will be far grander affairs than most of what's available today, with the exception of Old Trafford (albeit needing a refit, facility wise!) Therfore I'd have moved to a new venue rather than be forever encumbered and constrained by the past, however glorious!
Spurs have built what I'd consider a model stadium, facility wise, though too constraining capacity wise. We could have won on both those fronts, had we the motivation and financial courage to do so. Our bit part, fefurbished, facility stricken stadium will stand for a generation as a monument to financial cowardice, and lost opportunity.
As for the cost factor, financing large scale infrastructure was seldom easier, given the availability and historically low cost of longterm investment. Look around, it's happening everywhere, reflecting the uplifting presence of ambition, and unfortunately in our case, the dispiriting lack of it.
