On top of this, both Wolff and McLaren CEO Zak Brown have referenced a falling apart of Red Bull's technical team since the announcement that Newey would be leaving, with Brown claiming he had received CVs from Red Bull staff.
Speaking toSky Sports, however, Horner has taken a swipe at his Austrian counterpart Wolff and McLaren boss Brown, advising them to focus on their own teams' issues, while revealing that Red Bull have already poached over 200 of their rivals' employees to aid their own engine development.
Horner said: "The two candidates involved talk a lot. I'm not going to get sucked in for a tit for tat.
"I would be more focused on Toto's own issues that he has. I don't have any concern with the strength and depth [of Red Bull].
"Of course there is always going to be movement between teams. I don't know how many people we have employed by McLaren this year? Mercedes, we have taken 220 people. 220 out of HPP into Red Bull powertrains.
"So when we are talking about losing people, I would be more worried than about the 220 people, than one or two CVs."
