England head coach Jim Mallinder again names Leicester Tigers forward Martin in the second row – after starting as captain in the wins over Wales and Ireland – with scrum-half Van Poortvliet and wing Browning among the replacements.
Mallinder said: “What I want to see from the players on Sunday is how they adapt to a different threat and challenge from France.
“Ireland played with quite a structured style, they put us under a lot of pressure defensively and we struggled to get the ball but we defended well. We know France are going to be completely different and will challenge us in a different ways so I’m looking forward to seeing how we react to that.
“I also want to see the players enjoy this final match. We’ve have a good tournament so far, it’s been great that we’ve been winning but we’ve also been learning a lot as we’ve progressed through it.”
England against France is a 1.40pm kick-off at Kingsholm Stadium, Gloucester on Sunday, with live coverage on FreeSports TV.
