Reminds me of Barney Ronay's article a few years ago. The paradox is that for all the pretty triangles, we're relying on a pretty primitive means to get goals.

We stack the odds against successful crossing when the build up play is so slow and sides have time to regroup (unless we're willing to overload and commit the fullback, difficult if, for instance, Redmond holds his run when Bertrand advances as seems to be the plan). Never mind the actual quality of those crosses and the (un)willingness to commit players in the box.
