England could take charge of their own fate by defeating Italy heavily enough to surpass Ireland's superior points difference but with Joe Schmidt's side comfortably ahead on that front, Robshaw believes it would be foolish to do so.
Instead he must mull over how Gael Fickou's late try in Paris leaves England at the mercy of the day's two other challengers and then focus on completing their Italian job in Rome.
"The bounce of the rugby ball went against us in Paris and it can been brilliant or cruel for you," he said.
"On that day it went against us twice but we reacted well and have put ourselves in a position to win the title although we will always look back at the French match and think 'what if'.
"This year the pressure has been off us because we lost that first game with France and there wasn't going to be a Grand Slam," said Robshaw.
"It has been a massive test of character and resilience to put ourselves in contention.
"The attacking ability of the team has grown incredibly and we go into this game having to control our performance and then, like every other England fan, we will be cheering on France."
Stuart Lancaster's side are first up on Saturday and if they take care of their task in Rome they will be waiting around until late in the evening to see if they have secured a first RBS 6 Nations title since 2011.
To increase their attacking firepower Lancaster has opted to name fit-again centre Manu Tuilagi on the bench, while Matt Mullan travels as cover for Joe Marler whose partner is due to give birth.
For Italy the equation is far simpler - they must beat England to ensure they are not whitewashed in the 2014 Championship.
Italy are without prop Martin Castrogiovanni, who has failed to recover from injury but captain Sergio Parisse is fit to play. Lorenzo Cittadini takes Castrogiovanni's place in the front row while Matias Aguero replaces Alberto de Marchi.
And while Brunel admits the reshuffle is far from ideal, the Italy coach has called on his side to give everything they've got against England.
"Castro isn't available, so Cittadini will start," he said. "De Marchi will cover tighthead, he's played there before. It's not his best position but that's where he will play. We put Aguero in because in the second half we haven't had the impact that we wanted, and for that reason we thought bringing in players like Aguero might make a difference.
"We know when we play the English, you feel it the next day, physically.
"We really look at the time of the ball in play to judge the intensity of the game, and England have played three games which have been much more intense than ours.
"We don't want to lose faith in how we want to play the game. We need to know why we lost to Ireland, we've done the analysis but we are going to stick with our game plan. Hopefully we'll be able to carry it out on the pitch."
