Stuart Lancaster's side can become the first England team since 2003 to secure the grand slam, by beating all their opponents in the Six Nations.
Robshaw told The Sun: "You are always judged on your next game and this is exactly what this is.
"It's a huge occasion and there is a massive opportunity for us to become part of rugby history if we deliver what we've talked about.
"But it's one thing talking about it in training, another thing doing it in front of 73,000 people and those watching on TV."
England's clash with Wales at the Millennium Stadium kicks off at 5pm GMT.
