Hertha Berlin midfielder Alexander Esswein is the latest Bundesliga player to join the Common Goal initiative.
The 27-year-old midfielder follows the example of Bayern Munich's Mats Hummels, Hoffenheim coach Julian Nagelsmann and forward Serge Gnabry, Stuttgart's Dennis Aogo and Borussia Dortmund's Shinji Kagawa, in pledging one per cent of his wages to charity.
"I've been looking for a project which enable me to give something back to society for a long time, and I'm happy to have found this with Common Goal," Esswein explained in a video message.
"What strikes me most about the project is that it uses football to help the underprivileged. I hope more players can join the Common Goal initiative, because it is only as a team that we can make a a real difference."
Since its launch by Manchester United and Spain midfielder Juan Mata, a total of 20 players have joined the initiative.
All contributions will be pooled into a collective fund managed by Berlin-based non-governmental organisation streetfootballworld.
