Orlando Pirates' coach Jose Riveiro admitted that he is also puzzled by how the Buccaneers can be so dominant in knockout competitions but struggle to emulate that performance in the league.
The Spaniard, however, believes that the club is close to bringing their cup form into the DStv Premiership where they have been inconsistent.
Pirates moved closer to retaining the second of the two trophies they won last season when they beat AmaZulu 4-2 at Moses Mabhida Stadium in Durban to advance to the semi-final of the Nedbank Cup.
