Its not greed when he moved to a club in better shape than us, he's won multiple trophies and has turned into one of the best footballers about, its not like he made a sidewards step.
If he is greedy for joining a better team, then so is Alisson, so is van Dijk, so is... etc...
Well yes that's a logical point of view. But I personally can't bring myself to apply the same logic to somebody who wants to play for LFC as I do to somebody who didn't.
On the current PR initiative that him and his advisors have taken, I will be honest, if I didn't dislike him already I would be fairly uncomfortable about it. I acknowledge that Sterling speaking out helps the fight against racism and it that regard it's definitely a good thing. On the other hand, however, if a journalist wrote a piece similar to the letter he wrote about the differing attitudes to the two City youths buying houses for their parents, it would be considered lazy and inherently bias in itself.
Also if his comments about racism in football were not being delivered in tandem with numerous drip fed stories about his acts of goodwill and charity, I might be less likely to question the motives.
