Team A gets a penalty in their favour and allows their keeper to take it. Team B now gets the ball to the centre, everyone in their respected halves, touches the ball, shoots immediately and scores before the Team A’s keeper reaches back in his post.

My question is, does the referee have to check with both goalies before blowing the whistle to resume play?

My answer: (May 5, 2012):

No, the referee need not check with either goalkeeper at ANY restart.

Interestingly, nothing is said in the scenario about the referee whistling to signal that the kick-off could be taken. There is no requirement in the Laws of the Game that the referee check with the goalkeepers to see if they are ready. Failing that, and given that the kick-off is always ceremonial, it falls entirely to the referee to determine when the kick-off can occur, subject only to the requirements of the Law that each team must be in its respective half of the field. The referee is empowered to allow a corner kick (or a throw-in) to be taken even though the ‘keeper has not returned to the field of play, so there is no reason to assume that the goalkeeper, in his joy at scoring, should not return to his normal kick-off position for the KO to take place.

However, in a different situation, it is customary (but not required by the Laws) to allow players who have been substituted in for other players to reach their normal positions before any restart. This would be especially true of the goalkeeper.

To illustrate the first point, observe this videoclip (
