Pat Nevin on how teams gamble when defending corners

BBC Sport's Pat Nevin looks at how different Premier League teams set up to defend corners, and why some managers no longer leave men on the posts to stop the ball on the line.

Nevin believes teams are prepared to take the gamble of having no players on the goal line, in exchange for being able to break up the field from corners, and turn defence into attack.
