The club's decision to sign a former Axis paratrooper sparked protests, with 20,000 people attending a demonstration.
Over time, he gained acceptance through his performances in the City goal, playing all but five of the club's next 250 matches.
Named FWA Footballer of the Year for 1956, Trautmann entered football folklore with his performance in the 1956 FA (Football Association) Cup Final. With 17 minutes of the match remaining, Trautmann suffered a serious injury, after diving at the feet of Birmingham City's Peter Murphy. Despite his injury, he continued to play, making crucial saves to preserve his team's 3–1 lead. His neck was noticeably crooked as he collected his winner's medal; three days later an X-ray revealed it to be broken.
Trautmann continued to play for Manchester City until 1964, making 545 appearances.
