Cagliari Calcio manager Walter Mazzarri believes the introduction of Ghanaian youngster by AS Roma led to their defeat in the Italian Serie A.
Roma coach Jose Mourinho, who was suspended for the match instructed his assistant Joao Sacramento to introduce the untested 18-year-old early on in the second half when the Giallorossi were trailing.
Afena-Gyan flanked Tammy Abraham in attack for the remainder of the game and operating from the left as he caused a lot of havoc in the Cagliari penalty area.
Roma equalized through Roger Ibanez and captain Lorenzo Pellegrini drilled in a superb free-kick for the match winner.
Speaking after the game, the Cagliari manager said, “We were playing great but then that Felix Afena came in, I didn’t know him, I had prepared myself for Shomurodov, and he blew us away,”
Afena Gyan has been instrumental for Roma U-19 which caught the eye of the senior team’s coach.
