England scrum-half Ben Youngs has insisted that his side need to approach their Six Nations clash against Italy with the same intensity as they did in their win over Wales.

Stuart Lancaster's side got their campaign in the competition off to the perfect start with a 21-16 victory at the Millennium Stadium.

However, Youngs is adamant that the promising start will count for nothing if they fail to produce a good performance against Italy at Twickenham.

He told reporters: "That is the biggest challenge, to maintain the levels of performance from last week. That is one of the things we have focused on.

"Last time we played Italy at home, it was 18-11. That reinforces the fact that if you are not right on it, they will cause you problems. We have to back up everything we did last weekend."

England have won all 15 of their Six Nations matches against Italy.
