Invincible
Capello made his name as a manager with Milan in the early 90s winning four Scudettos (Italian league title) in five seasons. His side was built around the talents of the Dutch triumvirate of van Basten, Gullit and Rijkaard and between May 19, 1991 and March 21, 1993 the side went 58 league games unbeaten. That's a longer run than Arsene Wenger's 'invincible' Arsenal side of 2004.
