The People:
South Wales Constabulary are drafting in more than 800 officers to see off the threat of trouble at the Millennium Stadium, spending more than £1million on the project.
The FA and Government will share the cost, but it will be a small price to pay for quelling the threat of trouble between rival fans.
There is a three-way threat of violence because they expect Cardiff City fans to be out drinking among rival sets of supporters in the town centre on the Friday night.
