Johnson, the left-arm quick, retired from international cricket after the 2nd Test against New Zealand in Perth on November 17 (Tuesday).
The 34-year-old Johnson bid adieu to top-level cricket midway through the series with still one game (first ever day/night Test) to be played in Adelaide from November 27.
After playing 73 Tests, 153 ODIs and 30 T20Is, Johnson has singled out South Africa's AB de Villiers as the most difficult batsman to bowl at.
"AB de Villiers, he's one outstanding player of our generation. He was always so difficult to get out and a huge challenge," Johnson was quoted as saying by Cricket Australia's (CA) website.
"I remember the game at Centurion (in 2014) and I'd got a few quick wickets in that game and he came out to bat and looked so calm and composed and just played his natural game.
"It really is difficult when someone does come out like that and you're on top of your game. But it really is a great challenge and he's been one of the best players I've played against," he added.
De Villiers, who captains South Africa in ODIs, is regarded as one of the best batsmen across all formats.
Johnson finished his career with 313 Test, 239 ODI and 38 T20I wickets. He made his Test debut in November 2007.
