This is the annoying thing, people assuming that the players have unlimited reserves of energy, and are just 'fecking lazy and cowardly' have probably never played a real game of football in their lives.
When the body tires, a player can not simply just force himself to play at the level he played a few days earlier. You will hit a wall and mistakes are inevitable. I'm not saying I know what it is like to be a professional athlete, but I do know after a certain point all the effort and desire in the world won't help much.
I would love to see some of the lard-ass posters who post these abusive messages during and after, games like this, sit down with these professionals who have reached the absolute pinnacle of footballing success, and tell them just how rubbish they really are.
Because in person they would surely realize how ridiculous they are, and how little right they actually have to be criticizing/abusing such people, either online, or in person!
Then we would see who the real cowards are!
Yeah, posting snide messages on internet forums....
