England captain Dylan Hartley is looking forward to the "massive" challenge of facing South Africa in a November Test series.
Hartley led England to an historic Test series whitewash away to Australia since becoming captain in January, while England have also claimed the Six Nations Grand Slam in 2016.
Fiji, Argentina and Australia are also on the schedule for England and Hartley believes there is room for his team to continue their improvement under coach Eddie Jones.
"Every time I play for England I want to win, every series we go into I want to win and all our focus now is on South Africa and winning that game," Hartley said.
"I've never beaten South Africa, I don't think anyone in the squad's beaten them, so there's a massive challenge there for us.
"We as a team need to keep on improving and developing - whether that's in training or in games - and the autumn internationals are a perfect opportunity to play four brilliant teams."
England's training preparations have been overhauled, with 45 players involved in a recent two-day camp and another short meeting planned in October, with Hartley in favour of the amendments.
"We used to do a solid week somewhere but I like the way we've broken it down, I think two or three days here and there keeps us all connected and keeps us all in touch," the Northampton Saints player said.
"It keeps things fresh in the mind instead of turning up the week before the series and going 'right boys, let's go'. So I think it's a really good idea."
