CL, that is why I only train and not coach. Back in the day, I would usually reserve the comments for after the match.
Serioulsy, the officiatig has not kept up with the level of play. I see refs showing up to matches looking like complete slobs and are more concerned with what they are doing later that night and not what goes on in the match.
Refs also need to know the Laws and enforce it. For example, at my daughter's U14 match, they were up by 7 goals late in the match. The ref was not calling pushing from behind, etc. There was also a hand ball worthy of the Paraguayian National Team. The ref call it off and said, "You are up by many goals. I am jot calling any hands balls."
This stupidity goes against the letter of the Laws AND the spirit.
"...at the end of the day..."
