AUSTIN -- Daniel Ricciardo says he will not be afraid to express his frustration if Red Bull starts to favour teammate Max Verstappen over him.
Verstappen signed a new contract with Red Bull this weekend that will keep him at the team until the end of 2020. In the official announcement, team boss Christian Horner said Red Bull would build its team around Verstappen, raising questions over how Ricciardo fits into the equation long-term.
At this weekend's U.S. Grand Prix, Verstappen's car was fitted with the newest specification of Renault engine which, due to manufacturing constraints, is not expected to be made available to Ricciardo for the rest of year.
