4-3-3 Formation
From Soccer Manager Wiki
The 4-3-3 formation was a development of the 4-2-4, and was played globally by the Brazilian national team in the 1962 World Cup. The extra player in midfield allowed a stonger defence, and the midfield could be staggered for different effects. The three midfielders normally play closely together to protect the defense, and move laterally across the field as a coordinated unit. The three forwards split across the field to spread the attack, and are expected to "tackle back". Few teams often start a game in this formation, but may change to it late in a game if a goal is needed.
The 4-3-3 system allows you to have three attackers while still having a strong midfield.
A staggered 4-3-3 involving a defensive midfielder (usually numbered 4, 5 or 6) and two attacking midfielders (numbered 8 and 10) was commonplace in Italy, Argentina and Uruguay during the 1960s and 1970s. The Italian variety of 4-3-3 was simply a modification of WM, by converting one of the two wing-halves to a libero (sweeper), whereas the Argentine and Uruguayan formations were derived from 2-3-5 and retained the notional attacking centre-half.
