I think @santa sangria is pulling legsIt doesn't matter where the GK picks it up in the penalty area. They are not allowed to handle the ball from a throw in and should be penalised for it.
No, it's simply the fact that a goalkeeper may not touch the ball with the hands when it has been thrown-in by a team mate.So guessing the throw in was a pass back
An indirect free kick is awarded if a goalkeeper, inside their penalty area [...] touches the ball with the hands after [...] receiving it directly from a throw-in taken by a team-mate
Reds v Greens greens win a throw in close to the penalty area.Green throws to GK. GK picks up the ball I blow for an IDFK. GK says whats that for? I explained and there was one apologetic GK to his team mates.
