Franz Beckenbauer, the German soccer great who helped his country win the World Cup both as player and coach, has died, news agency dpa reported Monday. He was 78.

“It is with deep sadness that we announce that my husband and our father, Franz Beckenbauer, passed away peacefully in his sleep yesterday, Sunday, surrounded by his family,” the family said in a statement to dpa, the German news agency.

“We ask that we be allowed grieve in peace and spared any questions.”
