England head coach Eddie Jones wasn't entirely satisfied with his side's performance despite defeating South Africa comfortably at Twickenham.
A slow start left England chasing down South Africa's lead but once in front by half-time thanks to tries from Jonny May and Courtney Lawes they appeared in control.
The win is not only England's tenth of the year, keeping them unbeaten, but also their first over the Springboks for a decade.
"We're pleased with the result. Having not beaten South Africa for 10 years, to win by that scoreline today is fantastic," Jones said.
"We're certainly not satisfied with our performance. Areas of our game that really need tidying up.
"But it was our first game. We've got ten of the squad that went to Australia not here, so we've had to put together a new team, get people to understand how we want to play.
"We always thought that the first 20 minutes were going to be the most difficult. South Africa were going to come out hard, physical, be at us and they certainly didn't disappoint in that regard.
"But we regained our composure, control. I thought some of our attack today was good and some was very poor. Defensively we gave away a soft try at the end which was disappointing.
"All in all we get a pass mark today."
England lock Joe Launchbury was named Man of the Match as he packed down alongside Courtney Lawes, making his 50th Test appearance.
Jones was pleased with the preformances of both locks, who came into the side following injuries to the Grand Slam starting pair of Maro Itoje and George Kruis.
"It shows we've got great depth in the lock position," Jones added.
"I thought him and Courtney… Courtney's played his 50th Test and his next 50 is going to be better than his previous 50. Both of those guys did very well against what was a very good lineout.
"They picked three locks. So winning the ball in the lineout was always going to be difficult. We went about that and did it smartly, won the ball we needed to and used it well."
