Ghana U-20 Coach Sellas "Bobo" Tetteh has made two critical changes in his line-up for the must-win FIFA U20 World Cup tie against the United States of America on Thursday.The 2009 title winning coach has made two changes to his starting eleven leaving Inter Milan midfielder Alfred Duncan on the bench.Duncan, 20, has had his place taken by Tema Youth midfielder Moses Odjer.Francis Narh’s inability to link up well with Richmond Boakye-Yiadom in attack has cost him his place as Ebenezer Assifuah moves in to take his place.The central defensive pairing of Joseph Attamah and Lawrence Lartey is retained while Baba Rahman and Richmond Nketiah play from the left and right full-back respectively.Odjer comes in to join Seidu Salifu, Clifford Aboagye and Frank Acheampong in midfield.Ghana must record an emphatic victory over USA to stand any chance of progressing to the next stage of the competition after failing to win any of their opening two games of the tournament.Ghana line-up: 1.Eric Antwi 13.Richmond Nketia 14.Lawrence Lartey 4.Joseph Attamah 5.Baba Rahman 8.Seidu Salifu 19.Moses Odjer 7.Frank Acheampong 10. Clifford Aboagye 20.Richmond Boakye 17.Ebenezer Assifuah
