Verstappen: Horner has to get Red Bull back on track
Jos Verstappen has been unhappy lately with Red Bull's performances, with rumours suggesting he feels his son should move to Mercedes for next season.
Speaking to Bild newspaper, he said: "Over 20 seconds is a huge disappointment but that's not surprising when you reverse engineer the car.
"The team has taken the wrong turn several times. Internally, they should hold up a mirror and not always sugarcoat everything.
"It's time—if it's not already too late—to question themselves. The good people are leaving the team. I'm very unhappy with what's happening because Max cannot be happy with a car like this.
"Now it is up to [Christian] Horner to get the team back on track. I'll be surprised if he does. A lot has to happen for that. The whole spirit has to change."
