Here are some successful managers pictured during their careers as players.

The player in the centre of the back row of this photograph is Helenio Herrera. The team is Casablanca Roches Noires (1929).  As a manager in the 1950s and 60s he won La Liga 4 times, Serie A 3 times, The Fairs Cup twice, the European Cup twice, the Copa Del Rey twice and the Coppa Italia once. 

The legendary William Shankly of Preston North End. He guided Liverpool to 3 League titles, 2 FA Cups and a UEFA Cup. These figures mean nothing. His solid proletarian ethics and his philosophy of football cemented his place in the folklore of the game.

Guttmann Béla - Known outside Hungary as Bela Guttmann- the silk shirted dancing master who played at the heart of the great Hakoah Vienna side later won titles as a manager in Hungary, Brazil and Portugal ( he also managed clubs in the Netherlands, Romania, Switzerland, Austria, Uruguay, Argentina, Italy and Greece!) . He won the European Cup twice with Benfica, and his parting curse on that club remains potent to this day. 

Sir Matt Busby built 2 great sides at Manchester United, winning the European Cup, 5 League titles and 2 FA Cups. In his playing days he represented Liverpool and Manchester City.
