The 17-year-old striker opened his account for Pirates with an 86th minute equaliser in a 1-1 draw with Polokwane City at Orlando Stadium on Saturday night.
“It’s an amazing feeling to score my first senior goal and it’s one that I will remember and treasure forever,” Foster, who has been linked with a move to French giants Monaco, told Bucs' website.
“Every game that I play I wonder if the goal will come then, but now that I’ve scored I’m hopeful that they will keep on coming.”
The Amajita international continued: “The fact that we drew is not ideal especially after the good momentum that we carried going into this game from our two big wins in a row.
“I think I would have enjoyed scoring this goal even more had we won, but I suppose playing a part in keeping an undefeated start is the next best thing.
“I’m hoping that when I get my next chance, I can score as part of the winning team. After your first goal, it’s the winning team goals that are best to remember. I will never forget this one though.”
