Max Mosley admits it is "quite possible" Flavio Briatore is gearing up to return to Formula One.
The former FIA President last year oversaw the imposition of the ousted Renault boss' lifetime motor racing ban for the crashgate scandal.
But Briatore overturned that verdict in a civil court, before Mosley's presidential successor Jean Todt agreed to let the Italian and Pat Symonds back into the paddock in 2013.
It is rumoured that Briatore, 60, could return in a promotional role alongside his friend and business partner Bernie Ecclestone.
"It's quite possible," Mosley said in an interview with Germany's Welt newspaper.
"Should he come back, then it will certainly not be as team boss, but rather as a promoter or a manager of his drivers," he said.
Mosley acknowledged the rumours about Briatore possibly working alongside F1 Chief Executive Ecclestone.
"Bernie and Flavio are good friends and often go to lunch at a restaurant in Brompton Road, opposite Flavio's London office.
"That's all I know," said the 70-year-old.
Mosley said he is still in contact with Ecclestone "from time to time", but predicts trouble for the stability of today's period of peace.
"Within the parties that make up this sport - the teams, the FIA and Bernie Ecclestone - there is constant friction. The cooperation is extremely fragile," he warned.
"Strengthening the balance of this triangle is a major problem requiring a lot of skill," he said.
Epsilon Euskadi Yet To Complete 2011 F1 Budget
There are still "three candidates" in the running to occupy F1's 13th team entry in 2011, according to Joan Villadelprat.
He is in charge of the Spanish Le Mans team Epsilon Euskadi's bid, amid recent rumours the outfit had pulled out due to a lack of funding.
It has also been claimed that Epsilon Euskadi might instead merge with the struggling existing Spanish team, HRT.
"I don't know where that information came from," Villadelprat said in an interview with the sports daily AS.
"I spoke with Jose Ramon Carabante about a possible collaboration with us as a technology provider. We are looking for clients and it is clear Hispania is a potential client for the type of work that we do, provided there is no conflict of interest.
"But that's it, there was never any talk of a merger, even though I do not close any doors," he added.
Villadelprat said Epsilon Euskadi is still vying for the 13th team entry.
"The FIA knows our project well and now they must choose between the three candidates," he said.
"We explained our situation, including our financial one, making it clear that we have a commitment to provide the necessary budget even if the deal is not yet closed."
Echoing the claims of Jacques Villeneuve, who is bidding for the entry in collaboration with Durango, Villadelprat said it is possible the FIA will leave the 13th team place vacant.
Asked if he would be disappointed to miss out, he answered: "Not necessarily.
"Epsilon is more than F1; we are 130 people and would not risk our stability to go where we cannot be feasible."
