Pompey’s Asmir Begovic dispute is unlikely to be settled until the end of the year.
That is the verdict of David Lampitt as he looks to put to bed yet another legacy issue.
Spurs claim the Blues owe a £1m sell-on fee following the keeper’s departure for Stoke in February 2010.
It is alleged the clause was brokered on Pompey’s behalf by Daniel Azougy, who is reported to have a fraud conviction in his native Israel.
This was after Begovic pulled out of a proposed double White Hart Lane swoop which included Younes Kaboul.
Kaboul still made the switch in a £5m deal, while Begovic joined Stoke for £3.25m.
Regardless, Spurs believe they are entitled to £1m – something which has long been argued against by Pompey.
The debate is now going to a Premier League arbitration hearing.
Legal submissions by both clubs have already been made.
But Lampitt does not expect an outcome until the autumn.
He said: ‘There is a legal process ongoing.
‘While that is ongoing, there is not too much I can throw into the mix.
‘It won’t be heard for quite some time, I don’t think until the autumn.
‘There is a legal process to go through. That will carry on for a little while yet and we have to see that through.’
The club have this week revealed two other long-standing disputes have been settled.
Inter Milan have finally agreed to pay the outstanding £900,000 owed over their purchase of Sulley Muntari in the summer of 2008.
In addition, Genoa have settled the late payment of their £1.06m January instalment for Prince Boateng.
Pompey are still entitled to a fourth and final instalment of that summer 2010 transfer on July 1.
