How many players?

My lack of knowledge of sport and sporting matters is almost legendary. Interestingly though this seems to exist not only in my waking hours but also at a subconscious level. My mind is so uncontrollably (and unprofitably) busy that I often wake feeling that I have not actually been asleep and resting but rather living a parallel life. These two factors came together last night when in my ‘other life’ I was being asked to play for a football team! However this team was not one of the usual 5 or 11 a side. This team had 8 players per side, a number which even I recognised as abnormal. My quizzical expression received this explanation. ‘It’s like a normal five-a-side team but with three extra wicketkeepers!’
