The hit TV show Footballers' Wives has the chattering classes a-twitter with excitement. Today, following last night's episode, around coffee machines and water coolers all over London, professional men and women will talk of little else. The fictional characters who play on and off the pitch at Earls Park FC have us gripped, with their alcoholic excesses, their glamorous designer clothes, the sheer, fantastic tackiness of their houses. And now, amazingly, I'm out shopping with the real versions (none of them tacky, all of them glamorous) on a fresh London Sunday morning, in aid of a children's charity. So, what's it really like being a footballer's wife?
