"There are a lot of things to play out in the next week, the next two weeks and I'm just concentrating on getting this team to be in the right place for what's a massive game."
Lancaster has painted the week as similar to the lead-up to their stunning win over the All Blacks in 2012, having lost to Springboks the week prior.
Lancaster has made three changes to his side for the match, with lock Joe Launchbury, number eight Ben Morgan and centre Jonathan Joseph all included.
Meanwhile, Michael Cheika has kept faith with the starting side that won their opening match against Fiji before he gave his second-stringers a run around against Uruguay.
Cheika has maintained an outlook this week of not getting involved in England's business, but got close overnight when he suggested the hosts believe they have an advantage up front.
"I know they think we're weak in the forwards, it's pretty obvious - they're saying it out loud and they've done it to us, stuck it to us the last couple of times".
