Allison comment is incorrect - he did claim to be a City fan not just a follower (see earlier post from me about my indepth interview with him in 1992/3 for "Joe Mercer, OBE: Football With A Smile").
Of the others... George Weah comes into the category of 'it makes sense to say I'm a City fan because it may help when I arrive at Maine Road' and he was reported as saying he was a Blue, but I don't think any of us ever saw him on the Kippax.
Weah did claim that he was a City fan when he signed. And though people are cynical, there was a basis for it. I lived in France when I was a student in 1989-90 and Weah was then an emerging young player at Monaco. He formed part of a pretty lethal front pair alongside a nippy little Algerian (I think) guy called something like Youssouf Fofana. I wrote to Howard Kendall - the only time I ever wrote to a City manager - telling him he should look at both of them, but definitely buy Weah because he was going to be a great player.
Anyway, we didn't, and Weah went to PSG quite soon after that for about a million quid. But I always took an extra interest in him as the only alumnus of the Dyed scouting programme, and he definitely gave an interview when he was at Milan saying he'd followed City as a boy in the late seventies. MotD was the only foreign football they saw there, and everyone picked a team. He apparently chose us because we were actually pretty good back then and he liked the colour of our shirts.
Obviously he wasn't a die-hard Blue in the way lots of people are on here, and he'd never been to Maine Road when he signed for us. But he didn't just make up an allegiance when we bought him and he started talking about being a fan as a kid. Or at least if he did make it up, he'd invented it at least five years previously with no apparent reason for him to do so.
