Daniel Ricciardo dropped a bombshell when he informed Red Bull he would be leaving the team at the end of the 2018 Formula 1 season to join Renault. The ramifications that this development will have on the driver market are wide-ranging, and obviously start at the team he leaves behind.
Pierre Gasly appears to be the favourite to land promotion from Toro Rosso, but Carlos Sainz Jr is in the frame as well.
Which of those two should Red Bull pick? Or should it gamble spectacularly and try to reunite its new engine supplier Honda with a ghost from its past?
