Red Bull is planning to prioritise its 2019 engine deal over Daniel Ricciardo's new contract as it prepares to make a choice between Renault power and Honda power by the end of June.
After his victory in Monaco on Sunday, much of the talk surrounding Red Bull has focused on Ricciardo's contractual situation and whether he could be tempted away by rivals Mercedes and Ferrari. Red Bull has gone on the record saying it is keen to keep Ricciardo alongside Max Verstappen in 2019, but before entering negotiations with the Australian, team boss Christian Horner says both team and driver needs to know which manufacturer will be powering the car.
