Croatian striker Mario Mandzukic has forfeited a month's salary at AC Milan after he picked up an injury, with the club then offering the sum to a charity. The 34-year-old arrived at Milan in January on a six-month deal worth 300,000 euros a month. "This exceptional gesture shows Mario Mandzukic's professional ethics," AC Milan president Paolo Scaroni said, adding the money would go to a charity for youngsters. Mandzukic could return for Milan Sunday, with star striker Zlatan Ibrahimovic suspended. alu/dmc/lp
