The teenage Ghanaian midfielder, who signed for the Blues on transfer deadline day, has made an immediate impact in Norway despite being one of the youngest players in a competitive league.
Abu was on the bench on Sunday as Stromsgodset coach Ronny Deila kept faith with his cup line-up from earlier rounds to see through a 2-0 victory over Fallo FK, shock winners over champions Rosenborg in the semi-finals.
But the central midfielder with a powerful shot has figured in every league game and has made a real impression.
Norway’s winter break means Abu will be back at the club later this week before taking a well-earned break of his own. His loan lasts until next June, when Stromsgodset boss Deila seems certain to ask City for a repeat.
