Loose ends still to be tied uppublished at 13:03 British Summer Time 16 June
Clarke reckons there is a sense of understanding about what went wrong on Friday night.
He said: "We know what went wrong. I've spoken to the players about what I feel was wrong from my side, and what I gave them.
"I think their interpretation of what we asked them to do was wrong, so we've worked on that.
"To be honest, we haven't finished with that. We've got another pre-dinner meeting - the post-dinner meeting will be about Switzerland.
"We're still tidying up the loose ends of a really bad night."
