England coach Martin Johnson was left disappointed with his side's performance in the 41-10 win over Georgia.
England ran in six tries as they comfortably won the World Cup clash in Dunedin but Johnson was far from happy with his team's display.
The 2003 World Cup winners gave away eleven penalties in the first half and Johnson has told his team that they can forget winning the tournament if they continue to show such indiscipline.
"It wasn't good enough and if we are happy with those standards we'll go home early," said Johnson.
"The guys need to be a bit more patient and trust our defence. Some of it was sloppiness, a bit of rustiness maybe and the guys were a bit over-eager at times, but they have to learn they will be penalised.
"We need to be a bit sharper and we are under no illusions that we need to get better."
England next match is against Romania on Saturday, September 24.
