I guess there's a certain validity in the argument that big games should be played in as big a stadium as possible. In principle that's fair enough, but the Millennium Stadium /Arms Park is no more the traditional home of welsh football than Murrayfield is Scottish football (okay, there is a bit more history but still..)
I did wonder if the FAW would move this game to the Millennium before it was all rearranged, maybe it wasn't possible anyway, but credit to them for sticking with the CCS given they could have sold 40,000 more tickets in town
