5-3-2
5–3–2 formation
This formation has three central defenders, possibly with one acting as a sweeper. This system merges the winger and full-back positions into the wing-back, whose job it is to work their flank along the full length of the pitch, supporting both the defence and the attack.[79] At club level, the 5–3–2 was famously employed by Helenio Herrera in his Inter Milan side, influencing many other Italian teams of the era.[80] The Brazil team which won the 2002 FIFA World Cups also employed this formation with their wing-backs Cafu and Roberto Carlos two of the best known proponents of this position.[81][82]
5–3–2 with sweeper or 1–4–3–2
A variant of the 5–3–2, this involves a more withdrawn sweeper, who may join the midfield, and more advanced full-backs. The 1990 world champion West German teams was known for employing this tactic under Franz Beckenbauer, with his successor Berti Vogts retaining the scheme with some variations during his tenure.
