Le Havre are due a cut of Portsmouth's fee for Lassana Diarra.

Arsenal are already said to have a 25 per cent sell-on clause in their agreement and Le Havre insist they will also earn a tidy windfall from Diarra's expected sale to Real Madrid.

Chairman Jean-Pierre Louvel said during a press conference they will earn around £250,000 in the case the France international moves to the Santiago Bernabeu for £17 million.
