Ghana youth striker Ebenezer Assifuah marked his official debut for Swiss side FC Sion after coming off the substitute bench to play in their 3-1 victory over lower-tier side Sursee in the Swiss Cup on Saturday. The 19-year-old was introduced with 32 minutes of normal time left as he replaced Gaëtan Karlen as Sion fought from a goal down to claim a 3-1 win to advance to the next stage of the competition. The former Liberty Professionals prodigy set up the third goal for Sion as the tie had travelled deed into extra-time before a winner eventually emerged. Assifuah arrived in Sion on Thursday, passed medicals and trained with the side before Sion manager Michel Decastel included him in his 18-man squad for the trip. It was Sion’s first win of the new season in all competitions and winger Ishmael Yartey was hugely influential in the game as he set up two of the goals for Sion. Yartey also rattled the crossbar with a ferocious left-footed effort from 20 yards out.
