Eddie Jones thinks the best is yet to come from England after they completed a Six Nations Grand Slam with a 31-21 win over France on Saturday.
Jones' men survived a stern examination from Guy Noves' side at the Stade de France to emerge victorious, Danny Care, Dan Cole and Anthony Watson all crossing for tries for England.
It marks England's first Grand Slam since 2003 and represents a remarkable turnaround for a team that just five months ago was dumped out of the Rugby World Cup in the pool stage on home soil.
Next up for England is a Test series with Australia in June.
Jones told BBC Sport: "I'm very proud of the boys, We weren't at our best but battled through.
"I always had confidence in the team. I thought we sat back a little in the first half, but we were more positive in the second half.
"[Captain Dylan] Hartley has been excellent, and the nucleus of the team has been very strong.
"[Assistant coaches] [Paul] Gustard and [Steve] Borthwick have done fantastic work, and they must be congratulated for their efforts.
"The best is yet to come, we're heading to Australia and looking forward to that."
