England can dominate Six Nations for years - Castaignede

England possess the necessary talent to dominate the Six Nations for several years to come, according to former??France fly-half Thomas Castaignede.

A??29-18 victory for Scotland over France on Sunday meant Eddie Jones' side??secured a first championship since 2011.

England??can wrap up??the Grand Slam with a victory over France on Saturday, and Castaignede believes they will continue to dominate the tournament.??

"There are no other teams near England," the Frenchman, who??won Grand Slams in 1997 and 1998,??told BBC Sport.

"And if they keep the same group of players together they can win the tournament for many years.

"England have quality, are very well organised and Eddie Jones brings confidence.

"They deserve better than the title, they deserve the Grand Slam. I've been really impressed with England and the way they're playing."
