England captain Dylan Hartley has insisted that there is still more to come from his side following their 40-9 victory over Italy at the Stadio Olimpico this afternoon.

Just two points separated the sides at the halfway stage of the match, but England ran in four second-half tries, including a hat-trick for Jonathan Joseph, to pick up by far the biggest win of this year's Six Nations so far.

Hartley was pleased with how his side responded in the final half-hour of the contest, but admits that there is a lot to work on from a "frustrating" first half.

"The first half was frustrating, but overall it was a very satisfying win for us. We weren't 100% and we have got high standards, so we have got stuff to work on there," he told reporters.

"Breakdown-wise first half, we were a bit off the money, we were slow to get to the ruck, a few side entries, holding on to the ball, things we need to tidy up. I think we let Italy into the game there.

"We seemed surprised when they were competing for the ball, so second half we came out, we took the onus on ourselves to compete at the ruck a bit harder, get a foot on the ball, mix things up at the breakdown and I think it got us a good return there."

England will now look to make it three wins from three against defending champions Ireland in a fortnight's time.
