Football, I love you - but you're a dickhead.
Every time a player gets flaged for a foul or offside, and they do that dickhead thing of shouting at the linesman or wagging a finger ... I'd like them to review each and every decision after the match then apologise to the guy - or make a charitable donation of 1% of their gross salary each time the linesman gets it right.
The referee and linesmen don't sit there wagging a finger when the players shank wide off a simple scoring opportunity. If the match officials are able to maintain their professionalism throughout the 90 minute period, I see no reason the players shouldn't be able to reciprocate. It's hard to comprehend this being acceptable, let alone it being the norm in any other sport.
