The English Premier League and Football Association are likely to face sanctions for allowing domestic matches to be broadcast at the same time as European ties, contrary to a signed agreement between UEFA and the European Professional Football Leagues.

On Tuesday night, the Liverpool derby was shown live on Sky Sports at the same time as the Champions League matches between Internazionale and Marseilles, and Bayern Munich and FC Basle. Last week, ITV broadcast the FA Cup replay between Birmingham City and Chelsea on the same night as Arsenal versus AC Milan and Benfica versus Zenit St Petersburg in the Champions League, while the following night ESPN televised Tottenham Hotspur versus Stevenage Borough despite Champions League action on other channels.

That has angered the Scottish Football Assocation, who have written to UEFA for clarification after recently being told that Hearts' Scottish Cup replay with St Johnstone could not be televised as it would clash with Europa League ties, costing each club £82,500 of broadcasting income. Last season, St Johnstone also had to play two matches at 6pm so as to avoid being in direct competition with Champions League ties.

A UEFA spokesperson revealed that, on occasion, exceptions can be granted to allow domestic matches to be screened in competition with European games but that neither the FA nor the Premier League had received approval to broadcast the match between Liverpool and Everton. "There is a Memorandum of Understanding signed between UEFA and the EPFL (European Professional Football Leagues) which is also a basis for all national associations on the procedures and circumstances of use of UEFA dates," he said. "Top division matches cannot be on international match calendar dates, but exceptions are possible (eg force majeur). The game you mention of the English Premier League [the Liverpool derby] has not been approved by UEFA. The FA and the Premier League are aware about this and will face sanctions ."
