What is a fullback in soccer?

A fullback in soccer is a defensive player whose primary role is to prevent the opposing team from scoring goals and to support the team in the attacking phase. Fullbacks typically play on the outer edges of the defensive line, either on the right or left side of the field.

Fullbacks are responsible for marking opposing wingers and forwards, blocking shots, clearing the ball out of danger, and providing defensive cover for the central defenders. They also contribute to the team's attack by providing width, making overlapping runs to support the midfielders and wingers, and delivering crosses into the opponent's box.

Fullbacks are required to have good defensive skills, such as strong tackling, positioning, and marking abilities, as well as good stamina to cover a lot of ground and support both defense and attack. They also need to have good ball control, passing, and crossing skills to contribute to the team's attacking play.

Some famous fullbacks in soccer history include Paolo Maldini, Roberto Carlos, Philipp Lahm, Dani Alves, and Ashley Cole.
