I don't think Henderson is any worse than anyone else who signed in Saudi. Or for PSG. Or for City. Or for Newcastle. Or for Chelsea in the Roman era.So I will give shit to any player that took that money and doesn't use it to do a ton of good for others, but I don't think Henderson is worse than any of the other shameless whores.
(we can talk about how competitive the Saudi league is or is not, but that's not what people are "offended" about in this case - if he went for the same money to play in, let's say, Sweden, noone would mind... it's the human rights thing that's the issue, and if that's the case - and it is - Saudi, Newcastle, PSG and City are in the same boat)
He's won everything in club football. And even if he hadn't, it's entirely his right to go play there for stupid amounts of money.
