Cape Town - Orlando Pirates coach, Roger de Sa, says Sifiso Myeni’s introduction made the difference in their MTN8 semi-final second leg clash against Kaizer Chiefs on Tuesday.Pirates came from behind to draw 1-1 with Chiefs at Orlando Stadium, but advanced 2-1 on aggregate thanks to a 1-0 win in the first leg, last month.The former Wits midfielder replaced a tired Tlou Segolela after the interval when Bucs were still trailing after Bernard Parker had put Chiefs in front.Lennox Bacela equalised for Pirates from the penalty spot in the 76th minute to help the men in black progress to the final of the R8m competition. De Sa, 48, revealed that he had never celebrated the two consecutive draws in his career like he did on Tuesday. “I think Myeni's introduction was vital for us,” De Sa told the Kick-Off website.“We started to knock the ball around a lot more and Chiefs sat back.“In the end, we squeezed through and I have never celebrated two draws in quick succession like that in my life.” The Happy People were coming from a goalless stalemate against Egyptian giants, Al Ahly, on Sunday in their CAF Champions League encounter played at the same venue. Pirates will now face Platinum Stars in the final of the MTN8 at the Moses Mabhida Stadium in Durban this Saturday. Kick-off is scheduled for 20:15.
