David Coulthard says the sudden drop in form from McLaren and Williams demonstrates the sport doesn't respect history or reputation. He believes both teams must "reinvent" themselves following tough periods within F1, suggesting they should bring in new, younger talent.
Both teams have already announced changes going into the 2019 season. Between them, the two British teams hold 17 constructor's championships, but those days seem a long way from returning. Williams sits at the bottom of the Constructors' championship having picked up just seven points.
McLaren's last podium was 97 Grands Prix ago when Kevin Magnussen and Jenson Button finished second and third respectively at the 2014 Australian race. Since then, they've struggled to produce any results despite having big names in and out of the cockpit. Lando Norris and Carlos Sainz move in next year, producing some fresh faces.
Having driven and fought at the highest level for both teams, Coulthard finds it hard to watch how they perform. In his comments on BBC Sport, he provided some suggestions on how to reverse the current issues.
"It's confusing and disappointing to see the difficulty they have gone through. Success comes from the people, not the name on the door. It isn't self-sustaining. It is all about the people involved at any given period," Coulthard said.
"Clearly, both those teams have not been able to energise, reinvent and attract young talent and that is what they have to focus on. They need to change the structures they have in place and bring in the young talent. That is where the energy comes from."
So far, it looks like Coulthard will get what he's asking for. Williams is bringing in George Russell, a young British 19-year-old who will make his debut next season having performed well in the F2 series this year. The second seat at Williams remains unconfirmed.
