“… Using a 3–4–3, the midfielders are expected to split their time between attacking and defending. Having only three dedicated defenders means that if the opposing team breaks through the midfield, they will have a greater chance to score than with a more conventional defensive configuration, such as 4–5–1 or 4–4–2. However, the three forwards allow for a greater concentration on attack. This formation is used by more offensive-minded teams. The formation was famously used by Liverpool under Rafael Benítez during the second half of the 2005 UEFA Champions League Final to come back from a three-goal deficit. It was also notably used by Chelsea when they won the Premier League under manager Antonio Conte in the 2016–17 season and when they won the 2021 UEFA Champions League Final under Thomas Tuchel. …”
