The teenager was impressive on his debut as Djurgarden beat Orgyte in the Swedish cup semi finals
Donyoh, 18, came into the game in the 49th minute as a substitute and he really showed why Manchester City are so keen on him as he tormented the Orgyte backline with his pace and skills.
Skipper Andreas Johansson netted the vital goal for Djurgarden in the 59th minute and it proved to be the match winner.
Ghana midfielder Yussif Chibsah also had a great game and will be looking forward to the finals against IFK Gottenburg who also beat Oster 4-1 on Tuesday.
The winner of the finals slated for May 25th will play in the Europa League and it is evident that the Djurgarden Ghanaian trio of Chibsah, Amartey and Donyoh will be key to the fortunes of the club for the game at Friends Arena.
