Borussia Dortmund's Shinji Kawagwa is the latest player to sign up for Juan Mata's Common Goal charity initiative.
The Japan star, a former team-mate of Mata at Manchester United, is the 18th footballer to join the pledge to donate one per cent of his salary to a charitable fund.
"Football has given me so many opportunities in life and now I want to play my role in supporting others through the game," Kagawa said in a video posted on social media.
"Common Goal is quickly growing around the world and I'm proud to help lead the movement forward in Japan.
