Robshaw rues England indiscipline
Chris Robshaw admits England will reflect on the indiscipline that contributed to their downfall in Sunday's 19-9 defeat by Ireland in Dublin.
An inquest awaits this week as the Red Rose coaching team seek answers as to why 13 penalties were conceded, including two in the opening eight minutes that enabled the reigning champions to race into an early lead.
"Our biggest disappointment was our discipline," England's captain and openside said.
"When Ireland have a serious player like Jonathan Sexton who can nail goals and pin you in the corner, you don't want to give them any easy opportunities and allow them to keep the scoreboard ticking over.
"I'm not sure why it happened, but it is something that will be addressed throughout the coming week.
"We conceded some penalties due to pressure and some due to our own loss in concentration. I contributed myself as well.
"As a team you aim for under 10 penalties, that's the benchmark for the 80 minutes. If you do that you're in a good place. We gave away eight penalties in the first half and that pressure tells."
The Grand Slam has eluded England once more and they must now hope that Ireland slip up in Wales or Scotland to keep them in the title hunt, although in all probability they are likely to fall short for a fourth successive Six Nations of Stuart Lancaster's reign.
"We're extremely disappointed once again to have let it slip. It's once again out of our hands. We need a bit of luck now," Robshaw said.
"We have to put all of our attention into Scotland and see what happens in the last two games. We know it's out of our control.
"Credit to Ireland - they played well and were pretty smart about how they went about their business. They got the better of us. We were slightly off and they exploited us."
