Can't believe how much negative feedback this is getting. I'm the most cynical bastard of them all but I have to respect Mata for this because I don't believe he's the type to do something like this publicly to get more Instagram followers like some other players.
People asking him to donate 10% as well, get real, no chance of getting other players on board with that whereas if you make it 1% other players that get on board might well end up paying at least 2% or 3%.
Don't look at it as whether or not Mata deserves credit or not for giving up what is, for him, a pittance. Look at it as the guy trying to start a bit of a movement that could make a decent difference for a few charities.
