I'm staggered by the mentality of 'fans' that choose to boo their own players, especially during a game.
To try to justify booing an individual by saying that it might draw the manager's attention to a poor performance is frankly, ludicrous. As is the assertion that booing might somehow improve a player's game.
Conversely, I can think of plenty of examples when getting behind a player (or a team) when they're clearly low on confidence seems to spur them on. And that, I thought, is a part of what we're supposed to do as fans. It seems to work quite well away from home, at the moment.
I'm all for freedom of expression though. To those who choose to express that freedom by ceaselessly booing one player, expect to be challenged robustly and directly by those who disagree. No point in whining on here about it. If you're going to a game prepared to boo your own team, then be ready to get some stick for it. Freedom of expression cuts both ways.
So, those rude words that you're going to hear, and the boos directed at you - they're not personal. Even though I can see that they might seem a bit hostile and a bit upsetting, it's just people pointing out that as a fan your game isn't good enough any more. I'm sure you'll understand. Maybe it's just time for you to move on.
