England head coach Eddie Jones hailed his players after they secured a first Six Nations Grand Slam for 13 years by beating France 31-21 in Paris.
England repelled a strong French performance, scoring three tries, as they made it five wins out of five under Australian Jones' direction.
"I am very proud of the boys," Jones told BBC One.
"We weren't at our best today, but we battled through and really deserved the victory. It is a great achievement by the team.
"I always had confidence in the team.
"I thought in the first half we sat back a little bit, and were probably more worried about the result than playing, and the second half we were much more positive in the way we played."
Jones also praised captain Dylan Hartley, adding: "He has been fantastic, he has done a really good job. The nucleus of the team has been very strong.
"The two assistant coaches have done a fantastic job, Paul Gustard with his defence and Steve Borthwick with his set-piece work.
"The great thing is that the best is still ahead of us. We are only going to get better."
England centre Owen Farrell again delivered an impressive goal-kicking display, thriving in the Stade de France cauldron, with the visitors posting tries from Danny Care, Dan Cole and Anthony Watson.
Farrell said on BBC One: "It is brilliant. We set ourselves a goal at the start of the Six Nations to be the most dominant team in Europe, and we have achieved that goal.
"It wasn't the best of starts for us in the first half, even though we scored a couple of tries, but we showed some character in that second half. I thought the boys were brilliant.
"We were focused on our job. France are a good side, especially over here.
"This squad has been brilliant since we met up for this Six Nations. We have got better week on week, and built on performances. We got what we deserved after it.
"I am just chuffed for the boys. I am chuffed for everyone."
Number eight Billy Vunipola was arguably England's most influential performer across the championship, and he was thrilled by the Grand Slam achievement, which came a week after the title was secured.
Vunipola said: "This means a great deal. We have had a great eight weeks, and to come out on top and win every game after what happened at the World Cup, which no-one can forget about, it's a great achievement for us.
"I just thank God for giving me the opportunity, and I am just so happy right now.
"You could hear how loud the crowd was. I am sure they didn't want us to come here and win a Grand Slam on their home soil, and that is a credit to them.
"But more credit goes to my team and the way we stood up to them in a tough first half, and we eventually came out on top."
