Mea Culpa, I cocked up the maths, but the underlying point remains...
yeah, whilst there is an emotional aversion to selling the naming rights, there is a point at which it the financial incentive becomes too strong. £5 million a year, you can sod off, but if you are offering £15 million a year... that is very worthy of consideration. Of course the name would have to be somewhat respectable, the Smeg Stadium is not on really.
I wonder what companies would be willing and able to pay £200-300+ million over 20 years just to sponsor a stadium though. it would probably be an international company looking to expand to the UK. It is possible though - in the US, Citigroup are sponsoring the Mets new stadium (Citifield) paying $20million a year for 20 years. With our brand and the increasing popularity of the EPL around the world, some top companies could see Anfield as a chance to promote themselves globally and in the UK.
How much would it take, per year, for people to accept selling the naming rights?
