Simple really. Joe Hart f**ked up big time twice, that was the basic reason that we even managed a draw. He was our star man. The 3 Celtic players who are being hung, drawn and quartered on this thread actually played really well and are (IMO) being victimised for their single errors. But hey, why criticise the England goalie when you can fire missiles at Celtic players ??
Sometimes bias bubbles to the surface without the perpetrator realising they are guilty of it.
