Pompey are to go to arbitration in a bid to win their £1m Asmir Begovic wrangle.
The Blues have been in a long-running dispute with Spurs over claims they owe the White Hart Lane club a sell-on fee for the keeper.
It was a deal brokered by former finance advisor to Pompey, Daniel Azougy, in January – despite Begovic not being a Spurs player.
As part of the agreement, Harry Redknapp's club claim they are entitled to 1m of the fee Pompey received from the transfer which took him to Stoke.
That was seen as compensation after Begovic pulled out of an agreed White Hart Lane switch.
But the controversial deal has been one queried by former administrator Andrew Andronikou and now David Lampitt.
The Blues chief executive is taking the case to the Premier League, who will hold an independent arbitration meeting to settle the issue.
It is standard procedure to settle football disputes, rather than parties having to become embroiled in a court case.
A date for the meeting has yet to be confirmed, although it will be in the new year.
But Lampitt has revealed the club's desire to finally bring an end to the long-running saga.
He said: 'The Asmir Begovic situation is going to arbitration in the new year.
'This is an entirely- independent panel who will adjudicate on the issue and hopefully reach a conclusion.
'It is an issue which has gone on for a long time and needs to be brought to a close.'
Last year, the independent arbitration panel presided over Kevin Keegan's battle with Newcastle following his controversial exit.
More recently, Charlie Adam took his club Blackpool to arbitration last month over bonus payments he claimed he was owed, a case which the midfielder won.
