Russell Domingo was pleased with the sprit shown by South Africa after they ended a disappointing Test series with England on a high.
Impressive fast bowler Kagiso Rabada led the way on day five of the fourth and final Test with four wickets to end the innings with 6-32, recording match figures of 13-144, in Centurion.
Morne Morkel and Dane Piedt claimed the other wickets to complete a 280-run win, marking their first Test triumph since January 2015.
"The main thing I take out of it was the way the side responded to a lot of noise that has come from the public and the media," Domingo said.
"When you have one or two bad series, everybody makes you sound like you are the worst players and the worst coaches in the world, which is not necessarily the case.
"To play the way they have played these last couple of days makes the coaching staff really proud because it has been a tough series."
And the Proteas coach hopes to strengthen his backroom staff ahead of their next Test series against New Zealand in August to build on this momentum.
He added: "Everybody thinks we have not been looking for a batting coach but we've been trying for the last year.
"Every team's got it. England have got one, Australia have got one, India have got one.
"We've offered the position to quite a few people and we offered the position while things were going well, not while we've been bowled out for 80 and 90.
"We've had a few people who said they were interested but they wouldn't commit to it simply because travelling is not that fun when you are away from your family for a long time and when there is a lot of pressure and a lot of criticism you are faced with when things don't go well."
