Good post.
Personally, I'd never boo a player unless I genuinely thought he wasn't giving 100%
With the likes of Sanchez, for example, that's not the case. His poor performances were a result of low confidence combined with him simply not being good enough.
What's telling is that most of the faux outrage seems to be coming from the couch potato fans who spend every match day on here lecturing the match going fans spending their hard earned cash on their very expensive tickets.
If they feel the need to boo. That's up to them and I'd never think to patronising them by telling them how to behave or support their team
It just doesn't sit right with me I'm afraid. Comes across as a bit sneaky and grubby.
