Six Nations: Stuart Lancaster says England need to improve to defeat Wales

England head coach Stuart Lancaster says his team need to improve on their showing against Italy if they are to clinch a Grand Slam next week.

England forwards coach Graham Rowntree expressed the coaching staff's relief at clinching the result, specifically with the key lineout steal from Courtney Lawes with time running out. "Massive is an understatement," said Rowntree. "We've come through a massive scare there and credit must go to the lads for coming through that. The word 'lottery' is used often when it comes to scrums and it swung both ways today."
