Cape Town - Bulls coach Frans Ludeke has admitted that his team's performance against the Stormers wasn't good enough.
The men from Pretoria started their Super Rugby campaign on a low note when they lost 29-17 at home to their arch-rivals at the weekend.
"We came back well in the second half, but we can't afford to lose possession on our opponents' goal-line. It's definitely not how we wanted to start, but the Stormers were good," Ludeke told Netwerk24.
Ludeke also conceded that the ankle injury sustained by tighthead prop Werner Kruger was a major disruption.
"We were forced to throw Trevor (Nyakane) in at the deep end. He scrummed better towards the end and finished strong, but there were also key penalties we conceded that cost us dearly."
The Bulls' next assignment is at home against the Hurricanes this Friday (19:10 kick-off).
