Martin Johnson has told England they have one week to prove they have the self-belief to win tight games.
The England manager cut a frustrated figure after his side toiled to a 15-15 bore draw with Scotland in a Calcutta Cup clash which epitomised just how poor both teams are.
"Ireland was a game we could have won. It is a sign we haven't got the belief to nail those games," Johnson said. "I was frustrated with some of the penalties we gave away. We gave the ball back so cheaply in the first half. We did some very good things and did some silly things."
He added: "It added up to us not finishing off. Ultimately it was a tale of missed chances. Floody's kick was a couple of metres short at the end; it is those small margins.
"We just need to take that next step. As a team we have to find a way to win. We are trying to get better and trying to improve. Next week will be a step up from there.
"We have to stay with France because they try to blow you off the park in the first 20 minutes."
