All the goals came in a wild final half-hour, with Andre Ayew equalizing for Ghana eight minutes after Ronaldo converted his penalty after tumbling under a challenge by Mohammed Salisu.

Inaki Williams made his first competitive start for Ghana, a day after his brother, Nico, came on as a substitute for Spain in a 7-0 win over Costa Rica. Inaki Williams switched allegiance this year from Spain to Ghana, which is the country where his parents were born and left decades ago while his mother was pregnant with him.
Switzerland 1-0 Cameroon
Monaco forward Breel Embolo scored the only goal of the game to defeat Cameroon in the morning match in Qatar on Thursday.
