Each player and coach that has signed up has pledged to donate at least 1% of their salary. Some players may donate more than that - including Dennis Aogo, who has pledged 2%. Mata reportedly earns £140,000 a week at United, which will mean he is donating £72,800 each year. His contribution combined with those of Chiellini and Mats Hummels should put Common Goal around the £200,000-a-year mark straight off the bat, and may make £500,000 a feasible target in year one.
