Being realistic (and there'll be about 150 million reasons to be so) it's going to be The SPONSORS Stadium or The SPONSORS Arena. And if the club suggests some kind of amalgam sponsors will look at other examples and see they don't work....
Karen Earl Sports consulting director Tim Crow says: “There must be only one name, otherwise the media will edit it out. The sponsor relies on media mentions foremost – it is badging.” Crow points to Southampton’s [Friend's Provident] St Mary’s as an example of a sponsor being edited out, as well as Middlesbrough’s BT Cellnet Riverside stadium – a mouthful of a name, that was cut to Riverside long before the Cellnet brand ceased to exist.

I guess the stadium will end up with an official name or a project name whilst it's being built before naming rights are announced. But my guess if that's the case, is it won't be anything like as romantic as the 'Liverpool Waters Stadium'. I don't think it's a coincidence our new stadium scheme has the unmemorable "Northumberland Development Project" name attached to it at the moment, until its official sponsored name is announced. I wouldn't be surprised to see yours labelled - I don't know - the "Bramley-Moore Dock Regeneration Scheme" when (hopefully!) you get an announcement in the next few months.
