Ghana's all-time top scorer Asamoah Gyan has been called up to the Black Stars' squad for the first time in more than a year ahead of next week's Africa Cup of Nations qualifiers.

Ghana coach Kwesi Appiah announced on Monday his squad for the game against Sierra Leone in Kumasi on 11 October, with the 32-year old striker included.    

Gyan -- who last played for Ghana on 1 September 2017 and is currently playing at Turkish side Kayserispor -- was a surprise choice by Appiah, given that the veteran has only played for 35 minutes so far this season without scoring.

But Appiah seems to rely on the experience of the long-serving ace who had been a key figure for Ghana since making his debut in November 2003, playing 106 games and scoring 51 goals.

Meanwhile, Fenerbahçe and Crystal Palace strikers Andre Ayew and Jordan Ayew are still out of the team, which has fuelled speculation there is a rift between the coach and the Ayew brothers.

The Ghana Football Association (GFA) re-appointed Appiah as Ghana boss in May 2017 after Avram Grant resigned on the back of the Africa Cup of Nations held in Gabon in the same year.

Ghana are second of Group F with three points.
