An emotional Khune praised his former teammate for his dedication to the game and putting teamwork before his personal career having spent most of his time at Naturena as a second-choice, first to Brian Baloyi in 1999/00 and then Khune between 2009-2013.
"We lost a mentor in [Zizou] not only to me but many South African goalkeepers, he was very supportive towards his teammates," Khune said.
"Arthur was selfless. To prove that we currently have a player at Naturena, Brylon Petersen, who was brought in by him at a young age, and he didn't give up on him. I remember when he brought him for trials, he asked our then-goalkeeper coach Rainer Dinkelacker to have a look at him.
"He always wanted to see another player from Maritzburg succeeding. Bartman was a gentleman who understood teamwork."
Khune also shared the most memorial moment he will cherish of Bartman, whom he believes is among the people who contributed the most to his career and made him the goalkeeper he is today.
"He was always helpful, whenever coach Rainer was not available or sick, Bartman would takeover training, he didn't mind and always told me that we must always do things for the club and not for personal glory," he added.
Mamelodi Sundowns goalkeeper coach Wendell Robinson also shared his good memories of Bartman.
"We grew up together in this city, same age and made our professional debuts in the same year as I was playing for Moroka Swallows and he was at African Wanderers, we always had a good relationship," Robinson said.
"I was so happy to see him getting a chance at Kaizer Chiefs in his second stint where he showed the country what he's capable of. He was a fighter and always wanted to help. His dream was to become a head coach."
