It's amazing what this man does for people.racl101 3y agoTrue that. He's likeable too. That helps a lot.

If that isn't what you were claiming, apologies.criddell 3y agoMuhammad Ali was pretty big too.EstesPark 3y agoOf course, but not larger than Messi on a global scale - it's not even close.criddell 3y agoIn absolute numbers, sure.
