The South Africans eliminated Zesco via away goals after a 2-2 tie on aggregate following a 0-0 first leg draw in Pretoria last week.
“We knew that we need to come here (Ndola) and not necessarily win but to get a scoring draw and we would go through, and that is precisely what we achieved,” Tinkler said.
Winger Thuso Phala broke Zesco hearts with a stoppage time equalizer at the death to also complete his brace on the day at Levy Mwanawasa Stadium in Ndola. Zesco took the lead in the third minute but Phala levelled in the 33rd minute to even the tie at recess.
Defender David Owino put Zesco back ahead in the 48th minute before Phala ensured Matsatsantsa’s passage with his dramatic equalizer in added-on time.
“What we count as very important is what you do away from home rather than what you actually do at home,”Tinkler said.
SuperSport are home in the semifinal first leg on September 30 where they await Club Africain of Tunisia.
Meanwhile, Zesco United captain Jacob Banda has been mourning the exit from the second-tier continental club championship.
“This is a painful exit for us,” the goalkeeper said in a post-match interview.
“The blame is on us and not the coaches. We lacked concentration in the last minute. Our morale is low but football is like that,” Banda said.
It was the second straight year that Zesco were ejected from continental football by a South African opponent in the post-group stage. Mamelodi Sundowns eliminated Zesco at the semis of the CAF Champions League 2016 en route to lifting their debut title as African champions.
