England coach Martin Johnson wants his side to be "relentless" when they take on Romania in their penultimate Rugby World Cup Pool B match on Saturday.
The team were criticised for their performances following their wins against Argentina and Georgia.
"We need to be relentless", said Johnson. "We need to come out and play to a certain level to give ourselves the best chance.
"We've got to set our sights high, higher than they were last week (against Georgia). You can say it any number of ways but we've got to play a lot better."
England are currently top of Pool B, while Romania are bottom of the table.
