Black Stars head coach Kwesi Appiah says his side cannot afford to drop points against Ethiopia in their 2019 Africa Cup of Nations qualifier in Addis Ababa on Sunday.

Ghana were unable to play their AFCON doubleheader qualifier against Sierra Leone after FIFA suspended Sierra Leone FA from international football because of government interference in the running of the country's football association.

The West African country lost 1-0 to Kenya in Nairobi and are now third in Group F with three points, four below leaders Kenya.

Coach Appiah has fortified his squad by recalling the Ayew brothers as well as handing a call-up to the captain and Ghana's all-time top scorer Asamoah Gyan to boost their chances of qualifying to the competition.

"It's important to get a win to make sure we qualify then everybody will relax," coach Kwesi Appiah told Nation Sport after the session.

"All our players play abroad where they come fully prepared, knowing the situation, it's psychologically important to let them know we are going out for a win on Sunday.

"Ghana has lot of players, it's important you don't rely on what you have only. You always make sure you have a backup, only four players here made the Kenya game."
