The Brazilians have endured a difficult period on the continental stage, suffering a 3-1 defeat to USM Alger in the CAF Super Cup after their shock CAF Champions League elimination at the hands of Angolan outfit Wiliete SC last month.

The setbacks have raised questions about whether Sundowns need to strengthen their squad following last season's Champions League triumph.

However, Cardoso argues that comparisons between the current team and the group that reached consecutive continental finals and semi-finals overlook the significant changes within his squad.

The Portuguese tactician acknowledged that while his players possess quality, they still need to develop the experience required to compete consistently at the highest level.

"We have lost a lot of players, but we cannot complain. We know we are rebuilding, we know we have quality. Obviously, here and there, we don't have maturity, which is different. Quality is one thing; maturity is another to play these matches," he told the media.

Cardoso also highlighted the youthfulness of his current defensive department, pointing out that the centre-backs who featured against USM Alger were just 22 and 23 years old.

He further cited the absence of key figures such as Nuno Santos, Brayan Leon, Khuliso Mudau, Keanu Cupido and the late Jayden Adams as factors that have disrupted the team's balance.

The coach believes rebuilding the maturity that characterised last season's successful campaign will take time, particularly with several younger players still adapting to demanding continental encounters.

Despite Sundowns having already collected two trophies this season, Cardoso admitted that losing the Super Cup was difficult to accept, especially considering his expectations.

"So, it's a rebuilding process. But obviously, when you rebuild over more victories, it's fantastic, which we had a few, as it's clear, two trophies collected at this point of the season that we wanted. But I feel very disappointed today, I have to confess," he added.
