This past season Percy Tau and Rodney Ramagalela only netted 11 goals each to share the Golden Boot, the second lowest tally in PSL history.
Mashaba was asked for his opinion on the matter after Bafana were bundled out of the COSAFA Cup by minnows Madagascar on penalties following a goalless affair in Polokwane last weekend.
"Yes, we are having a problem and most unfortunately we tend to isolate ourselves from the world," Mashaba said.
"Going with the question of scoring goals, I want to mention one player, former player Jomo Sono. I played with him at Orlando Pirates. That man would stay on the field after a training session with 36 balls on the ground; hitting bananas, curling the ball, doing this. But you don't see that anymore, nothing.
"Everybody, when the coach blows the final whistle three times, everybody shaya iskhiye, yachitha [is going to their cars and is leaving], AmaVroo Praaa, breee, breee and they are gone.
"Whatever we did then it’s no more. When you come to the next session the following day there must be a rehearsal problem and you say, 'Mnuna, I'm giving you 10 balls, let's see how many you can score. I checked you yesterday you scored this. Defense we need to cover this way, that way. How do we do it?' And goalkeepers as well."
Mashaba was sacked as Bafana coach in December 2016 after being found guilty of 'gross misconduct, insubordination and violating SAFA's communications policy' at a disciplinary hearing.
He was previously indefinitely suspended from his coaching duties the month before following a tirade aimed at the SAFA hierarchy after Bafana's 2-1 win over Senegal in World Cup qualifying.
