Robshaw: We have to be perfect for Dublin
Chris Robshaw knows England's pursuit of the Grand Slam will be ruined by Ireland if their build-up to the Dublin showdown is anything other than perfect.
The Six Nation' only unbeaten teams will collide on March 1 in a third-round appointment pivotal to the outcome of the title race.
England continued to plot their route to a first Championship crown under Stuart Lancaster by dispatching Italy 47-17 at Twickenham, engineering six tries in an emphatic winning score.
But by their own admission it was a flawed victory, with the leaking of three tries and the gifting of an early lead against outclassed opposition the chief shortcomings to be addressed.
Robshaw has revealed England's preparations for the curtain raiser to World Cup year at Twickenham were temporarily affected by the afterglow of their outstanding victory over Wales.
"For the first couple of days after Cardiff you did see bit of an emotional hangover, so to speak. But come Thursday and Friday we were spot on," Robshaw said.
"We need to be right on the button mentally for Ireland. They're an extremely good side who have an extremely smart coach in Joe Schmidt. He generally finds weaknesses somewhere.
"It's about making sure we're clued up, that everyone does their job as well as possible when we get there.
"And the details need to be spot on because we need to try and find their weaknesses as well.
"We got the result we wanted against Italy. We know we weren't great at times, but to get a good scoreline like that and get what we wanted out of the game was very promising.
"Every game is decisive. You need to make sure you beat what's in front of you."
