Learn English – Phrase for asking the obvious

I'm sure the reporter knew perfectly well the implications of using to coin a phrase, and it wasn't an "ironic" usage in the sense that people say this when trotting out a cliche. It's a tichy (tongue-in-cheek) example of typical British understatement.

Barry Kilby (manager of Burnley Football Club) has said more than once that he wouldn't bet the ranch on the outcome of an upcoming game. The reporter is slightly niggled by this, since the standard (particularly in the UK) expression is bet the farm. She's even more niggled because we don't even have "ranches" in the UK - but we do have a preponderance of foreign (including American) managers of our football clubs.

Personally I think the reporter is taking two or three good-natured pops at what she sees as legitimate targets, while showing her own skill at writing by doing this in so few words.

Edit: Having not actually followed OP's link to the newspaper report itself until now, I've just somewhat sheepishly changed the gender of my pronoun references to reporter Suzanne Geldard.

It’s true that this expression is in an interrogative form that is not normally found in contemporary English. It uses inversion rather than the auxiliary verb do. We would normally expect What do you have? (or, in the UK at least, What have you got?) It’s a colloquial way of saying, in the Oxford English Dictionary’s definition, ‘anything else (similar) that there may be, or that one can think of’, or even, simply, etcetera. It’s of US origin, and the Oxford English Dictionary’s earliest citation is from the 'New Yorker' magazine in 1925.
