But Uefa said in a statement: “These rules ensure that any cross-border competitions are assessed on objective, transparent, non-discriminatory and proportionate criteria.
“This development comes after the European Parliament this month adopted a landmark resolution explicitly reiterating its opposition to ‘breakaway competitions’ as they ‘endanger the overall sport ecosystem’.
“Uefa will carefully review the judgment before deciding on any further steps, and will not be commenting further at this stage.”
Uefa added it will continue to “safeguard the unity of European football” and it is “firmly committed to the European sports model, built on sporting merit, open access, solidarity and the protection of the football pyramid”.
