Ghana have one foot in the last round of the 2019 Africa U23 Cup of Nations qualifying following a 4-0 thrashing of Gabon on Saturday.
An Osman Bukari double and a goal each from Spain-based Kwabena Owusu and Germany-based Bernard Tekpetey gave the Black Meteors a resounding advantage in the second round first leg fixture at the Accra Sports Stadium.
Ibrahim Tanko's charges must now earn a favourable result in the return match away in Gabon on Tuesday to book a place in the final round.
The winners will face Equatorial Guinea or Algeria in the ultimate decider in June.
