Abdallah Sima secured the Czech Cup for Slavia Prague with his match-winning goal in their 1-0 victory over Viktoria Plzen in Thursday's final match.
After a goalless first-half, the 19-year-old replaced Lukas Masopust in the 60th minute and he went to on to separate both teams in Plzen with his effort in the 73rd minute.
The victory completed the domestic double for Slavia Prague after they clinched their third successive Czech Liga title last month.
Ivory Coast duo Ibrahim Benhamin Traore and Simon Deli were also introduced as second-half substitutes for the Red and Whites while Nigeria’s Peter Olayinka was not involved in the encounter.
