Hummels pledged his support to collective fund Common Goal, a charity run by the Berlin-based streetfootballworld, which represents a group of 120 charities in 80 countries.
Hummels is reported to be payed €150,000 (US$176,000) a week by reigning Bundesliga champions Bayern Munich.
Bayern Munich defender Hummels is the second high-profile international player to pledge one per cent of his salary to the charitable foundation.
He joins Manchester United forward Juan Mata, who became the first footballer to back the initiative earlier this month, in giving his patronage to Common Goal. At the time, Mata appealed for 10 other players to follow his example and create a 'Common Goal starting XI'. The Spaniard admitted that although he doesn’t “know Mats personally” he was “pleasantly surprised when he contacted me to talk Common Goal”, adding that Hummels would be the "perfect team-mate" for his goal.
