David Coulthard warns Sergio Perez about a potentially uncertain future at Red Bull similar to Daniel Ricciardo.

Red Bull adviser Helmut Marko has confirmed that the team have offered Daniel Ricciardo an F1 lifeline with an ambassadorial role. And he doubts that the Australian will want to continue his racing career in another category of motorsport after being dropped by Red Bull junior team VCARB this week.

Ricciardo was always intended to be Red Bull's safety net. But fluctuating form and a series of decisions leaves the veteran out of F1.
