I expect Pete is referring to a combo of holding player / attacking player which does tend to be the favoured approach these days. I wouldn't call it a diamond so much myself, that's just Sven bullsh1tology & I expect it strictly refers to the "wide" two playing narrower than having conventional wingers.
An obvious exception is the way Barton & Ireland interact at City. I heard the term "piston" to describe the Vieira / Petit pairing at Arsenal & it kind of refers to City aswell.
