England completed a successful autumn with wins against South Africa, Japan and Australia marred only by a narrow defeat to New Zealand.
In the injury-enforced absences of Jonathan Joseph and Manu Tuilagi, Slade featured in all four autumn internationals, starting wins over Australia and South Africa and the single-point defeat to New Zealand.
And former England captain and centre Will Carling took to social media to praise Henry Slade's performances during the series.
Having fulfilled a variety of roles during his career, including inside centre, outside centre and fly-half, the 25-year-old now feels he has finally settled into his best position.
He said: "I'm pretty pleased with how I've gone in the autumn. I feel more and more comfortable and more and more confident after each game.
"I've had a good run of games at 13 now and that's been a thing I've had in my career, I have never been able to have a long run at one position, but I think at 13 I've been able to have a good crack at it now."
He seems to have flown under many radars, but I think @Sladey_10 has had a very impressive November. Some great touches, crucial impact at breakdowns strong defense and is perfect skilful link between Teo/ Farrell/Tuilagi and outside backs 👏🏽👏🏽
