In the course of 155 pages, no detail is considered too fine, no issue deemed too trivial. From the level of glare given off by the stadium lights to the size of a club mascot — “only slightly larger than a normal person” — the manual issued by UEFA to every entrant in the Champions League, soccer’s most glamorous club competition, covers it.

A vast majority of the teams preparing for the first round of group games this week, of course, will know many of the rules and regulations by heart. Bayern Munich, Barcelona, Juventus and the defending champion, Real Madrid, are here every year.

They know that each dressing room should contain three individual seated toilets, that there must be space on the covered substitutes’ bench for 14 people, and that the sponsor’s logo on a goalkeeper’s gloves must not exceed 20 square centimeters.

They will already have the position of the compulsory “beauty camera” — placed to offer a panoramic shot of the stadium — fixed in their minds. Their groundskeeping staff will be aware that each half of the playing surface must contain nine stripes of uniform width, the first four of them precisely 5.5 meters. The staff preparing the team’s gear will remember that the 600 Respect badges the clubs will be sent should be affixed to the left sleeve of all shirts, not the right, just as the equipment man will have set aside space to store the 84 official Adidas match balls he will receive.
