Jens Gerhard Lehmann is a German former professional footballer who played as a goalkeeper. He was a member of Arsenal's "Invincibles", playing every match of their unbeaten title-winning season. He holds the UEFA Champions League record for the most consecutive clean sheets, not conceding a single goal in eight consecutive full matches while he played for Arsenal. He also has the highest number of continuous minutes without conceding goals. In total, this lasted 853 minutes. He is regarded as one of the best goalkeepers of his generation.

In English football, "The Invincibles" is a nickname used to refer to the Preston North End team of the 1888–89 season, managed by William Sudell, and the Arsenal team of the 2003–04 season managed by Arsène Wenger. Preston North End earned the nickname after completing an entire season undefeated in league and cup competition, while Arsenal were undefeated in the league in a run that stretched to a record 49 games. The actual nickname of the Preston team was the "Old Invincibles" but both versions have been in use although Arsenal is the only team to ever finish a 38 match season undefeated.
