Speaking to The Times, Irish FA’s chief executive, Patrick Nelson said: "The data that’s coming out of it so far is very, very interesting, in that the two trials so far have been that if the goalkeeper is holding on to the ball too long, the referee will award a corner. The instances of corners being awarded are almost non-existent, which would indicate to us, certainly looking at the data, that the deterrent is exactly what we would want it to be at this point, and it’s speeding up the goalkeepers letting go of the ball and bringing it back into play."
He added: "The wrath of any coach for any goalkeeper who’s given away a corner or a throw-in that leads to a goal is always certainly going to mean the goalkeeper is not going to do that twice. It’s going to change goalkeeper behaviour."
