The 2008 United (compared to the 1980 version) is a very successful, massively profitable club that gets 75,000 at home and sells ton after ton of merchandise around the world. More and more of their money comes from people who live thousands of miles away and have never even heard of Altrincham. There is no point trying to compete with them directly.
If we were offered money to host some of their youth games and stuck our noses up at them as a point of principle they would no doubt go to one of the many other non-league clubs in this area who would probably bite their hands off. We would lose out on a few grand in the long run, United would lose out on nothing. If being associated very loosely with United makes more people aware of Alty, I'm all for it.
