POLL: Who should replace Daniel Ricciardo at Red Bull?

With the news that Daniel Ricciardo will be leaving Red Bull to join Renault in 2019, the team will be quickly on the phone to drivers up and down the grid with a view to replacing the Aussie. Who do you think should get the drive at Red Bull? Carlos Sainz and Pierre Gasly have their Red Bull link already but what is Fernando Alonso up to next year?

Will it be one of the Red Bull drivers from Toro Rosso? Carlos Sainz re-partnering Max Verstappen at the senior team this time? Or a left-field appointment?
