Orlando Pirates head coach Josef Zinnbauer says Sagrada Esperanca made things difficult for his side with their man-marking system on Tuesday afternoon.
Pirates secured a narrow 1-0 win over the Angolan side in the Caf Confederation Cup first-round first-leg encounter at Estadio Municipal dos Coqueiros.
The only goal of the match was scored by Thembinkosi Lorch with 16 minutes left on the clock.

Zinnbauer was pleased to see Bucs record an away victory in tough conditions in the capital city of Angola, Luanda.
"It was a tough game for us, the weather was very hot and the field was not so good - there was long grass and bouncy [field], a little bit for the ball," Zinnbauer told Pirates' media team.
