Sofiane Boufal’s 82nd-minute strike helped Morocco to a narrow win over Group C rivals Ghana in their Africa Cup of Nations opener.
The former Southampton winger pounced on to a loose ball before hammering his effort into the far corner.
It was a rare moment of quality in an otherwise uneventful game as four-time winners Ghana frustrated their opponents.
Morocco were untroubled in the closing stages, cantering to their win.
The late goal saw a quick triple substitution by Milovan Rajevac as he brought on Fatawu Issahaku, Benjamin Tetteh and Daniel-Kofi Kyereh.
But it was the Atlas Lions who looked more likely to score again as Saiss headed wide from a free-kick before Wollacott was forced into a brilliant late save.
The Black Stars will play Gabon in their second game on Tuesday, 18th January, a must-win game for the Stars to increase their chances of progressing to the next stage of the competition while Morocco, on the other hand, face debutants Comoros.
