But are you paying your £45 to expect the players in front of you to perform, or because you want to support your team?
For me it's the latter. I want the team to do well, and as such I don't think it serves my purpose to boo the players, destroying their confidence and their ability to perform as a result. They may be earning millions, but that doesn't make them any less susceptible to lack of confidence brought on by needless abuse.
If you're just paying £45 to moan at rich people... well take a step back and realise how stupid that is!
