Roy Hodgson runs through the key aspects of a 4-4-2. Using Italy's World Cup winning side as an example. The 4-4-2 is probably the most common formation in all of soccer.
Hodgson coached Switzerland to the World Cup birth in 1994 and the Euros in 1996. He has coached a range of clubs teams all over the world, from Inter to Blackburn to Grasshoppers to FC Copenhagen to Udinese. He's now the boss for Fulham in the EPL.
