Blue Bulls head coach John Mitchell has said all his team need to do in Saturday's Currie Cup semifinal against the Sharks at King's Park is to focus on their own strengths.

Whatever strengths those could be, something is clearly functioning well in Pretoria as the Bulls squeezed into the semifinals on the back of two big wins against the Free State Cheetahs and the Pumas.

They were on the receiving end of some harsh rugby lessons against the Sharks in both their round-robin matches, but they showed some fight in their 18-5 and 28-20 defeats.

"At the end of the day, it's going to be a race to see who initiates their strengths the better and I guess that's what the contest will be all about," Mitchell said.

"We are two different teams, but we know the Currie Cup is not our destination as we will continue to build for the future. If we choose to go further as a result of a good performance, that's great, but we're building for the future.

"The Currie Cup would be a by-product of getting our things right, but I won't be drawn into the outcome as much as that's enjoyable because it can also go the other way."

The Sharks have been extraordinary for the better part of this season. After their first game loss to the now-eliminated Free State Cheetahs, they embarked on a 10-match winning streak that was snapped by a desperate Western Province side who were chasing a home semi.

Mitchell is aware the Sharks may be hurt and could want to make an example out of them.

"We're another step closer now, but we've drawn the best team in the competition. They've got the home semifinal for a reason, but we need to stick to the processes that we've stuck to since Nelspruit," Mitchell said.
