"We showed a lot of character out there," said Barker, who guided Bafana Bafana to their only Afcon title. "We showed that we can still play a bit and Zane (Moosa) and Doc (Khumalo) reminded me of those glory days.
"I think they were brilliant and I have said this in the past, but Mark Fish was phenomenal as well.
"I thought Jerry (Sikhosana) took his goal very well and Doc had the crowd on their feet.
"Football is entertainment and I'd like to believe we gave the spectators what they wanted."
German coach Eric Rutemoller said the South Africans were worthy winners of the game, which was played in honour of the late Bafana Bafana assistant coach Thomas Madigage.
"We knew the South Africans were technically good and very, very skilful," Rutemoller said.
"We aimed to close them down but it proved simply impossible - especially their No15 (Khumalo) who really had a fantastic match as he controlled the pace of the game."
Sikhosana came off the bench for Phil Masinga and curled in a beauty past German goalkeeper Oliver Reck in the 47th minute to give the South Africans the lead.
Khumalo crowned the afternoon's performance by slipping the ball in from under the diving Reck after a great through ball from Moosa in the 57th minute. A soft penalty was converted by Marko Rehmer as the German side bagged a consolation goal in the dying stages. - Sapa
