Foster, who plays his club football with Westerlo in Belgium, opened his account for Bafana Bafana on Thursday when he netted the opening goal in South Africa's 2-1 defeat to Morocco in the country's first 2023 CAF Africa Cup of Nations qualifier.
The former Orlando Pirates starlet latched onto a pin-point pass from debutant Sphephelo Sithole before outmuscling Paris Saint-Germain star Achraf Hakimi to fire home with just eight minutes played on the clock.
"It was nice to finally score my first goal for Bafana Bafana after some time," Foster told SAFA's media team.
"It's definitely a special moment for me, my family and my community but it was a bitter-sweet one because we didn't end up winning the game. All in all, it was a nice moment for me but it would have been sweeter if we had got the three points."
