Lawyers have shot down claims by Manchester City that the Premier League’s associated party transaction (APT) rules should be considered “void” following the club’s partially successful legal challenge.

In a letter to the other 19 top-flight clubs, Manchester City general counsel Simon Cliff said APT rules – designed to prevent clubs benefiting from artificially inflated sponsorship deals – should be disregarded as a result of Monday’s verdict by an arbitration panel.

The English champions challenged the regulations’ compatibility with competition law on 25 separate points. They succeeded on two points but saw the other 23 rejected, as the panel broadly backed the Premier League’s aims and methodology.
