England could secure a fifth successive and record-breaking Six Nations crown, and the all important Grand Slam, with victory over France at the Stade Velodrome in Rennes.

But Spencer is aware of the threat France pose and wants the team to attack the game with the same intensity that has seen them concede just five points this campaign.

She said: “As we head towards the France game we are exactly where we want to be in the table, and we are coming off the back of an impressive win against Scotland.

“However, playing France in France is always a tough encounter. France have been playing some great rugby in the tournament and are close on our heels in the table having only lost just one game; like us they have everything to play for.

“It's vitally important to us that we play with control and composure throughout the full 80 minutes. The French always come out in full force to support their international team and that creates an atmosphere which is unique to this part of the world. If the crowd falls silent we know we are doing our job on the pitch.

“With the next big tournament for us being the World Cup in August and the fact that victory on Friday will bring us the Grand Slam, it makes this an even bigger game.

“However, we will only allow that to enter out thoughts following the final whistle. As players we have complete clarity in our minds as to what our target is in the run up to this game.

“We want to beat France in Rennes on Friday night. At this moment in time nothing else matters.”
