Football

Successful first time (player)-managers in no particular order:

1. Johan Cruijff
   
2. Kenny Dalgleish
   
3. Pep Guardiola
   
4. Zinedine Zidane
   
5. Glenn Hoddle
   
6. Gianluca Vialli
   
7. Ruud Gullit
   
8. Franz Beckenbauer
   
9. Carlo Ancelotti
   
10. Didier Dechamps
    
    

There’s plenty more and there are also plenty of failures (Giggs/Ince) but I doubt there’s a stat out there that tells you that you need to start in the lower leagues to become a successful cup winning manager.
