Goals from Khuliso Mudau, Brayan Leon and Iqraam Rayners sealed a clinical home performance, putting Sundowns firmly in control ahead of the return leg in Bamako.

Historically, the South African champions rarely let such leads slip. They have never lost a two-legged tie after winning the first leg 3-0, and across 23 knockout ties where they led after the opening match, they progressed 21 times. Even when they stumbled in second legs, they often still advanced - most notably in 2016, when they lifted the trophy despite losing away to Zamalek.

Sundowns' consistency in attack also underlines their dominance. In 46 second-leg matches after winning the first leg, they failed to score only five times. That record could prove decisive again, with an away goal likely to end any realistic hopes of a comeback.

However, Cardoso refused to entertain any sense of comfort.

"Champions League is an open game," he said. "Football shows us every day that things can change. We cannot think the story is finished - it must be controlled by us."

The warning comes amid belief from the hosts that a comeback remains possible. Former Stade Malien forward Lamine Diarra insisted his former side have not given up.

"We gave everything in the first leg, but conceded three goals," he said. "The result was a surprise, especially with how strong the team has been defensively.

"If Sundowns scored three at home, why can't Stade Malien do the same? The spirit is still strong, and the players understand what is at stake. They are ready to fight back."

Despite that optimism, Sundowns' experience and record in these situations make them clear favourites. Yet Cardoso's message was simple: stay focused, stay disciplined, and finish the job.

"The Champions League is not written yet," he added.
