Another player wouldn't simply have risked it, because it's not like he's playing for a team that's going to compete anyway.
I'm still United fan and will never support Liverpool for anything even if they have an Egyptian player, feck them, but Salah is a pure footballer, not provoking anyone, no haircuts, no tattoos, no stupid celebrations, just plays, scores and goes home. You hardly see these kind of players these days so I don't think he's worth hate or having fun of him. His only problem is he plays for Liverpool, which another great season in England and he'll leave and this problem will be done for.
