I'm not quite sure how anyone can know what anyone else is booing about.
When a player is subbed off and the crowd boos - how does anyone know if it's the player, the sub, the manager, the tactics or the length of time it's taking the make a sub that's being booed?
My point is that regardless of what the aim is, what's the point? What positive effect can booing possibly have on any of the above cases? If a manager made a substitute just because fans wanted them to make that substitute... then they really shouldn't be a manager - we should just crowd source substitutions using an app if that's the case (not a serious suggestion - just pointing out the sillyness of it all)
it's all good and well sitting at home in your undies watching on your laptop in regards to the booing
but when your at the ground ( baring in mind this is not a freak result it has happened all season now ) watching the same garbage every single week it's frustrating, no one was getting booed directly not even cuco the clown.
it's always at HT/FT to let them know what they have just served up wasn't good enough
or the decision to bring a striker off for another striker when we are losing atg home to the second bottom team in the league
what good does it do? well after the game the media took notice and asked fat sam about it, he knows now that the [Poor language removed] he is serving up every single week isn't good enough and wont be accepted at this club. if we just clapped that off he'll probably finish the game thinking we're all happy with a point
if we Koeman weren't getting booed after the sh1te he served up he might still be here now
