Portsmouth are considering taking legal action against the Premier League over its decision to divert television revenue away from the crisis-torn club, according to chief executive Peter Storrie.
Pompey have missed out on £7million this week and remain under a transfer embargo after the league stepped in and paid the latest round of television money owed to the club directly to their football creditors.
Portsmouth still owe money to other clubs for the transfer of players and earlier in the month were threatened with a winding up order by HM Revenue and Customs.
But following the latest financial blow, Storrie has revealed that the Premier League's bottom club are considering their options.
"I can confirm we have issued a legal letter to the Premier League to demand that the transfer embargo should be lifted," he told the Sunday Mirror.
"We believe we've a very good case against them. They have absolutely no right to withhold TV money in advance of future payments or payments to foreign clubs."
Pompey are believed to owe money to Premier League rivals Chelsea and Tottenham for Glen Johnson and Younes Kaboul respectively.
Italian side Udinese and French clubs Rennes and Lens are also reported to be football creditors.
