Cape Town - Sundowns head coach Pitso Mosimane believes SuperSport United had the better of his side until they changed tactics late in the game and handed over the initiative.
Despite taking the lead in the 27th minute through Sibusiso Vilakazi, Sundowns were on the back foot for much of the encounter but that all changed in the 75th minute.
SuperSport shifted gears and began bombing long balls in search of a quick counter attack but it just allowed the Brazilians to defend a bit more effectively.
"A difficult game for us, I think SuperSport played in two formats. They looked more dangerous and a better playing team when they were passing the ball around and they made us to defend a lot," Mosimane said after the game.
"But they changed the strategy when it was 15 minutes to go and they played into our hands…they played the long balls and we have Mosa (Lebusa) who took out all the aerial balls.
"Ricardo (Nascimento) took all the aerial balls, (Motjeka) Madisha took them same as Anele (Ngcongca) they are good in aerial strength and that did not help them.
"I think they could've hurt us if they continued playing the way they were playing. But we played the level of Champions League. We can play quiet, loud. Tonight we played quiet and we are through to the final (second round)."
The result was marred by a potentially very serious injury to Thapelo Morena.
"I haven't got the full update on him. Very sad, we need Thapelo for Champions League and I think the ankle came off, I don't know but I think they managed to put it back. I'm not sure about that," Mosimane added.
"The pitch is soft so I think it [Morena's ankle] got stuck in there and couldn't get the leg out. Disappointed with that because we need him for Champions League and we need him for the rest of the season. But football is a professional sport so these things do happen."
