Just as many so-called Christians pick out the bits of the Bible that appeal to them and ignore the rest, so do most socialists pick the bits of socialism that appeal to them and ignore the rest.
To be perfectly honest, I do not see how a top PL club can conceivably be 'socialist'. It's like being a 'Christian' and running a brothel and casino. You can call it a Christian Brothel and Casino, but by definition, it isn't.
A socialist football club, if such a thing could exist, would be entirely community-based. It would not seek profit, and it would certainly not have players on millions a year. Or managers/directors for that matter. You might, I suppose, run that model in League Two, but even there it would be a bit of a stretch.
