Mercedes boss Ross Brawn believes the changes in personnel coming at Red Bull will weaken the current four-time world champions.
In the next year the Anglo Austrian team will lose top aerodynamic chief Peter Prodromou and his deputy to McLaren as well as questions over medium-term future of their designer Adrian Newey.
“I don’t think any team can lose someone of that experience and calibre without it having some impact,” Brawn said of Prodromou to The Guardian.
Another move that will have an impact, Brawn added, is James Allison’s switch from Lotus to Ferrari.
“James Allison has gone from Lotus having designed a very good car there, to Ferrari, and I am sure next year their car will be a lot better,” he said.
“That’s the nature of the business.
“It happens in F1 all the time. Red Bull are where they are because they took Adrian (Newey) out of McLaren. It’s the nature of F1.”
Brawn also spoke about the outbursts from Lewis Hamilton over the radio during the US Grand Prix on Sunday.
Early in the race while in a battle with Mark Webber his engineer came over the radio telling Lewis to look after the tyres; ”That’s what I’m doing man, let me focus,” was his response.
Though towards two-thirds race distance after the period of quieter messages Hamilton came back on the radio saying: ”You need to give me some feedback, man — tyres, temperatures.”
When asked about the 2008 champion’s conflicting messages Brawn replied: ”We are just getting used to working with Lewis. It’s not problematic.”
Hamilton also said that he apologised to his engineer post race: ”The poor guy has come on the radio and then I come back at him -– I will always say sorry.
“Stuff does not come out like ‘Hey buddy, just give me a little moment here’. It’s like you are holding on to a bull and it’s like ‘Give me a frickin’ second!’”
