Can we make a unofficial rule that we will not mention

[Rich]

no he doesn't, he has to be 2 meters away from the point at which the throw is taken. He can be right on the touchline if he is 10 metres down the pitch

So the chap could have just taken the throw in from a little further back, you mean?

he could have but he didn't, so Alexis was in the wrong and a free kick was awarded

The free kick could only be given for simulation - can't give a free kick for not retreating as that link says

It shouldn't have been a free kick anyway as the by the time, Alexis "reacted" the ball was out of play. Should have booked Alexis, booked and then red carded Fuchs and restarted play with another throw
