England coach Stuart Lancaster 'frustrated' by missed opportunities against Scotland

England coach Stuart Lancaster has bemoaned his side's lack of cutting edge after a dominant performance against Scotland was rewarded with just three tries at Twickenham.

Jonathan Joseph, George Ford and Jack Nowell all scored as England retained the Calcutta Cup to give Lancaster's team a three-point advantage over Ireland going into the final weekend of the championship.

Points difference is expected to dictate the destination of the title, with main rivals Wales and Ireland travelling to Italy and Scotland respectively, while England host France in the final game with their fate in their own hands.

However, Lancaster was left irritated by a number of missed opportunities during the game which ensured England's lead in the Six Nations is only wafer-thin.

"From a performance point of view we're delighted with the opportunities we created but equally we'll look back at the tape the think with the tries that were disallowed and opportunities we missed it is frustrating without a doubt," he said.

"We'll wait and see what happens next weekend. We'll know our own destiny come that final game. You can get too carried away you have to beat France you've got to beat France first an foremost.

"If we'd score four or five tries as oppose tot here we'd be sat in a better position but we didn't.

"You don't get try scoring opportunities without good attack. You could see in our intent to play, our breakdown work was sharper and more effective.

"We created 12 breaks but to only convert three is frustrating and I think the boys are frustrated in the changing room. We'll need to be sharper to beat France."
