Helmut Marko has kept firing amid the war of words between 2010 championship rivals Red Bull and Ferrari.
Marko recently likened Ferrari's hiring of strategy boss Neil Martin as a move to poach Red Bull's "spirit", prompting Luca di Montezemolo's retort that the Austrian team doesn't "know how to behave as champions".
"This was all blown up by a newspaper," Red Bull consultant and driver programme manager Marko insisted, according to Auto Bild Motorsport.
The saga did, however, highlight the relationship between the two sides, with both Ferrari and Red Bull to use a Magneti Marelli KERS next year.
"We are both working with Magneti Marelli as the basis (of the system)," confirmed Marko, "but the real development will take place in the fine details."
Another common ground between the two sides is sister team Toro Rosso's Ferrari engine supply, but on this matter Marko poured fuel onto the fire.
"We stand to learn nothing from Toro Rosso's customer engines, which - anyway - are not on the same level as the real Ferrari engines," he said.
Toro Rosso will use Ferrari's KERS system in 2011.
