Bernd Reichart, the chief executive of A22 Sports Management, was speaking at an economic forum event in Spain attended by Real Madrid and Barcelona presidents Florentino Perez and Joan Laporta.

The two clubs, which along with Juventus are the holdouts of the 2021 attempt, saw an argument that UEFA's governance is an illegal monopoly on continental football struck down by the European Court of Justice on Friday (AEDT).

But Reichart has refuted the idea the competition's hopes of coming to fruition are at an end, pointing out the ruling is non-binding, with a final decision due next year.

"The Super League isn't dead, not at all, it's very much alive," he said. "We'll keep working until the judgement.

"We are still convinced that UEFA can't be everything at once. They organise the competition, they regulate the competition, and at the same time they control access to the market."
