Agree with you on Stockdale's reaction, Dunk looked desolate at that moment.
But I really don't think you can have a go at the fans last night. Put it in context. It has taken a lot for them to lose patience with Dunk, who came through as a youngster and we all want to do well. We are not...
I have no idea whether Dunk actually said those words in the OP...but after the blunder for the goal he definitely reacted angrily towards the crowd in the East Stand following the ironic cheering. Something was said, and it wasn't pretty.
If I was Dunk I'd be more worried about letting down...
