Medeama coach Samuel Boadu is worried that Ghana could face difficulties against Ethiopia in the 2019 Africa Cup of Nations qualifiers without midfielder Kwadwo Asamoah.
The 29-year-old has been ruled out of the November 18 clash in Addis Ababa after he suffered an ankle injury last weekend in Inter Milan's 4-1 away defeat to Atlanta in Serie A.
Despite the return of the Ayew brothers and the availability of legendary striker Asamoah Gyan, Boadu says Ghana need to double their efforts in order to secure full points.
"In recent time, Kwesi Appiah wanted to rely on Kwadwo Asamoah's quality in his game plan in a bid to qualify Ghana for the tournament so his absence will definitely affect the team," he told Goal.
"Now the coach must change his game plan to suit those available and that is not going to be easy. The team will struggle but I trust him to do a decent job in Addis Ababa on Sunday.
"This fixture is obviously the biggest game for the country in the qualifiers because of the defeat to Kenya and the ban which has been handed to Sierra Leone by Fifa. It is now a must win regardless any obstacles, so the players must give their best.
"With the return of the Ayew brothers, the technical team can plan something around them together with Asamoah Gyan so that Ghana will avoid a defeat or stalemate but it won't be that simple," he added.
Kenya lead Group F with seven points, four points above Ghana, who will not qualify if they lose against Ethiopia.
