NEWCASTLE United’s £7million pursuit of Bafetimbi Gomis remains on a knife-edge.
The Magpies are furious with Marseille for attempting to hijack their bid for the striker.
Lyon have reported their rivals to the French football authorities for approaching the 28-year-old without permission.
Newcastle’s director of football, Joe Kinnear, has been involved in protracted discussions with Lyon, Gomis and his representatives after agreeing the fee.
But talks have become bogged down over payments and commissions due to agents involved in the deal.
Marseille’s intervention also hasn’t helped, though the Stade Velodrome club have now signed Saber Khlifa from Evian.
Reports in France have suggested one sticking point has been the percentage of the fee Gomis and his representatives are due to receive from Lyon.
However, the player’s personal terms aren’t thought to be an issue, and Gomis remains keen to join United.
Lyon owner Jean-Michel Aulas has repeatedly gone public with developments in the saga, and he briefed French journalists , saying: “I am very disappointed that the deal was never finished with Newcastle. Personally, I am very pessimistic. Someone is pulling the strings behind the scenes.
“I have filed a complaint. Things will be settled in front of the appropriate committee (of the French league).
“It is a complete disservice to Bafe. He is a player that we respect. For the moment, the situation is blocked.
“On August 30, if no solution is reached we will reintegrate Bafe in the squad. We will have to change our approach to Bafe’s situation.
“Our desire is to settle things positively for everyone involved.”
Aulas also suggested Gomis – who has a year left on his Lyon deal – could sign another contract at the Ligue 1 club.
Meanwhile, there has been no progress on a deal for Darren Bent, another of Newcastle’s striking targets. Aston Villa are holding out for a £6m fee for Bent, who is also wanted by Fulham.
Newcastle are unwilling to pay more than £2m for a player who will turn 30 over the course of the new season.
As it stands, the Magpies’ only signing is Loic Remy, on a year’s loan from QPR.
