Neil Armstrong and Buzz Aldrin were defenders.
What's this, you ask? Just a map of the pair's wanderings on the moon, superimposed onto a football (soccer) pitch. As best one can tell the Moon XI liked to attack down the right-wing, forcing the intrepid astronauts to play a rugged, hoofing, defensive game. Aldrin never made it out of the Earthlings' half, while Armstrong only ventured a single foray towards the opposition penalty area. Of course, we were playing away from home and it always takes some time to acclimatise to, let alone deal with, the intimidating atmosphere at Moon Park.
