Christian Horner has taken a swipe at Toto Wolff after the Mercedes boss was joined by McLaren man Zak Brown in questioning Red Bull over the exit of Adrian Newey.
“You know the two candidates involved. They talk a lot,” Horner told reporters.
“I’m not going to get sucked into a tit for tat but I’d be more focused on Toto’s own issues that he has.
“I don’t have any concern about our strength and depth. Of course there is always going to be movement between teams.
