"We have won 13 of the last 15 matches over three years in the Six Nations. We are undefeated in France in seven matches since November," he said.
"We have also got the record number of points since 2000 in the Six Nations. This team is going to go a long way."
Coach Bernard Laporte was more guarded, adding: "We are not yet world champions but we are proud of these players."
France won four of their five matches in this year's Six Nations, their only defeat coming against Scotland in the opening round of matches.
But they clinched the title by beating Wales 21-16 in Cardiff.
Laporte admitted his team had not produced their best performance at the Millennium Stadium but was quick to lavish praise on Welsh scrum-half Mike Phillips.
"We weren't brilliant around the rucks and breakdowns, but we must congratulate him. He had a very good match today," said Laporte.
"We missed three high balls at the start, missed tackles and had the yellow card (shown to Raphael Ibanez) but we didn't panic and that was important.
"No-one jumped ship and we all stayed together and we have to congratulate the squad and our captain Fabien Pelous for leading them."
Pelous said his team's Six Nations success had exceeded his expectations.
"At the beginning of the tournament we didn't think we would win the trophy but we worked a lot and now we can take the trophy to France," he said.
"For that I am very proud of my players."
