Corner Kick Rules Explained: What an Olympic Goal Is

A corner kick is the restart awarded when the whole of the ball crosses the goal line, outside the goal, after being last touched by a defending player. It is taken from the corner arc nearest to where the ball left the field, and a goal may be scored directly from it. That direct strike, untouched by anyone else, is what South Americans and the French call an Olympic goal. Everything else about the restart, where the ball sits, how far opponents stand, when play resumes, is set out in Law 17 of the Laws of the Game.

The ball must be stationary and placed inside the corner arc, a quarter-circle of one metre radius, although part of it may overhang the line, since the line belongs to the area. The corner flagpost must not be moved or removed, not even to give the taker a cleaner swing. Opponents have to remain at least 9.15 metres from the arc until the ball is in play, and the ball is in play the moment it is kicked and clearly moves. The taker may not play it again before another player has touched it.

Several details trip people up. A goal can be scored directly against the opponents, but never against your own side: if the kick curls straight into the taker's own net, the opposition receives a corner. Nobody can be penalised for offside when receiving the ball directly from a corner, though offside applies again once a teammate has touched it. Short corners, played sideways to a nearby colleague, are entirely legal, and even a goalkeeper may take one. If the ball is placed outside the arc, the kick is simply retaken.

The nickname dates from 1924. Uruguay had just won the Olympic football tournament in Paris and, meeting Argentina in Buenos Aires soon afterwards, conceded a goal driven directly from a corner by Cesareo Onzari. The Argentine press teased the Olympic champions, and the phrase gol olimpico spread across the continent; the French adopted but olympique, the Italians gol olimpico. British football never coined a nickname, which is why the same feat is described plainly here as scoring direct from a corner, a rarity that still empties the terraces of doubt.

The rarity is physics as much as skill. The kicker must bend the ball across and back towards goal, exploiting the sideways spin known as the Magnus effect, while keeping it beyond a goalkeeper who can see the whole flight. An in-swinger struck with the foot furthest from the touchline curls goalwards naturally, and wind, a crowded six-yard box and an unsighted keeper all help. Because any touch by another player cancels the feat, the ball must travel a curving path of twenty metres or more without being interfered with.

Two myths persist. The first is that the ball must leave the corner arc before it is live; it only has to be kicked and clearly move, which is why a tiny nudge already puts the ball in play and lets a teammate run onto it. The second is that offside can never be given from a corner at all, it cannot be given on the first pass, but it certainly can once the ball has been touched by an attacker. Referees may also caution players who repeatedly encroach inside the required distance.

In the modern game corners are rehearsed like training-ground choreography: designated deliverers, blocking runs, zonal or man-marking cover and a defender posted on the goal line. Against that organisation the direct corner survives as a happy accident of technique and geometry, half intention and half gust of wind. The law has barely changed for generations, which is part of its charm: the same quarter-circle, the same immovable flag, the same chance that one curling delivery bypasses twenty players and settles in the net.
