The World Cup provided the old war-horses with their international swan song and Laporte admits they will be difficult to replace.
He said: "We're in a rebuilding stage. Fabien and Raphael were very big players for us, they were very important.
"That sort of experience is very hard to replace and we will miss them. "
Laporte also acknowledged that England have also lost a legend of the modern game in their captain Martin Johnson.
"But England have injuries and of course Martin Johnson has retired - he was a great player and they will not be quite the same without him," added Les Bleus' trainer.
"But they have so much depth that they will be able to replace him."
