Percy Tau shot wide for South Africa midway through the first half before Morocco took control of a dull game after the break.

The 1976 winners almost went ahead after 64 minutes when Hakimi's 25-yard strike rattled the underside of the bar.

Five minutes later, Morocco should have broken the deadlock only for En-Nesyri to miss a golden chance when he shot wide after rounding Ronwen Williams.

En-Nesyri also headed straight at Williams before Boussoufa fired in an 90th-minute winner after South Africa failed to clear a free kick.
