Stuart Lancaster insists work to be done

England coach Stuart Lancaster has insisted that his young team still have work to do despite crushing Fiji at Twickenham this afternoon.

Lancaster watched his side score seven tries in a dominant display, with Manu Tuilagi and Charlie Sharples both bagging braces.

Despite delighting a packed Twickenham crowd Lancaster was quick to point out that tougher tests lie ahead this autumn.

He told Sky Sports News: "It was good to get the win. We struggled a bit for 10-15 minutes. We didn't convert every opportunity but we were pleased with the opportunities we did take.

"It was a good start but we recognised the quality of the opposition that is coming around the corner. We will have to step up a couple of levels next week.

"Next week against Australia and the week after and the week after that we are going to have to be more clinical."

England take on Australia next Saturday before completing their Test fixtures for 2012 against New Zealand and South Africa.
