Mosimane ran from his technical area to the corner flag to join his players in celebration after Mahlambi hit the last nail in the Egyptian side's coffin at Lucas Moripe Stadium on Saturday.
"When I recruited Phaka, it was difficult for Phaka. He said awungilande [come fetch me] coach, I am in a jungle, I am alone, nobody talks to me. I don’t even go to training, nobody asks me where I am, I am training alone. They even went to pre-season and left me alone," Mosimane revealed.
"It was emotional for a 21-year-old to be left like that. I said Phaka I will do my best, one thing I promise you, I will bring you back. I knew it will give him a small chance and it was the right time to score.
:It was emotional for him and emotional for me because I struggled to get Phaka and I am still yet to get Phaka right. He is a youngster, he is 21 years old. Yes, he has a big name at the moment but he is 21 years old, he needs a lot of support and so when he scored that goal it was emotional for me to go there.
"I didn’t go there because it was five goals, I could have gone there every time they scored but that one meant a lot for him and me because I know the youngster needs help and support. I hope he scores again in Egypt."
