It would be very nice to play in the City of Manchester Stadium! Might have a much bigger catchment area.
Personally with my most favorite-st best team in the whole wide world (i.e. Saracens), I think we should demolish part of North London (I mean, nobody will miss it, its only Watford) and build an uber stadium with all the seats black and red and on one stand "named the "Les Noirs" stand, we could form an image of Andy Farrell's face using seat colours! And we could have like super laser shows where they get to write "Saracens R brill" and "O'Gara, you smell of wee" and "Carlos, you're a ponce!" in the sky.
Also there'd be a big sign saying "NO STANDING" and everyone would be forced to sit in wheelchairs so that nobody would have seized up joints like me and each seat would have a pint and food holder!
Best. Stadium. Ever.
