Red Bull chief Christian Horner said "everyone" should be concerned about the pace of Racing Point this season after Renault protested the legality of their car on Sunday (12 July).
Renault lodged a formal protest in the aftermath of Lewis Hamilton's victory in the Styrian Grand Prix, a race that saw Sergio Perez storm from 17th on the grid to sixth in his Racing Point.
The Renault protest claims that Racing Point has breached Formula One's rules by building a car that is not original in design of specific 'Listed Parts'.
