Red Bull could be set to lose another key figure to McLaren according to a report in German media.
Auto Sport und Motor believes the deputy to the already departing Peter Prodromou is also set to make the switch from Milton Keynes to Woking though as of yet it is not confirmed.
Last weekend in Suzuka it was confirmed that Prodromou, seen as the 'right hand man' to design genius Adrian Newey, would be making the move when his current contract expires, though that may not be until 2015.
"The content of any contract is obviously confidential," said Red Bull boss Christian Horner to reporters, "but it runs for quite a while yet and we are certainly in no rush to release him early."
Now though Auto Sport und Motor reports the "number 2 in the aerodynamics department" will also be joining, though the article did not give a name to the engineer in question.
Red Bull's only response came through motorsport adviser Dr Helmut Marko who said "We'll see in a year where the two men are working."
Though McLaren boss Martin Whitmarsh seemed much more certain of a double arrival from Red Bull.
"We have had signed contracts with them for some time," he said. "We respect the fact that they are still under contract to Red Bull, but they will work for us in due course."
Meanwhile speculation over the future of Mercedes' top man Ross Brawn is still rampant.
In Suzuka the 58-year-old issued a clear quit threat to his management team at Brackley but Chairman Niki Lauda has moved to quell the rumours.
In Japan amid talk Brawn could return to Honda for the future McLaren tie-up, he told Britain's Sky Sports: "We need to make sure if I'm to remain here that I'm the reference."
But with former McLaren tech chief Paddy Lowe waiting in the wings such assurances may not be coming. Lauda claims, however, Mercedes does want Brawn to stay.
"We have had some small problems in the team in the past but everything is sorted now," the great Austrian is quoted by the Mirror.
"It's all agreed between him and Paddy and everyone else. He's number 1.
"I have tried to persuade him to stay," Lauda added. "It's down to him now. I'd say it's 50-50."
