#4 Esteban Ocon
At number four is Force India's Esteban Ocon. Now this is also an interesting one. The Frenchman looked set to rejoin Renault after he was a reserve driver back in 2016, but with that door now firmly shut, could a move to Red Bull be on the cards?
Red Bull will, of course, be looking for a talented replacement for Ricciardo and Esteban Ocon certainly fits the bill. He has done well while at Force India but with a junior driver with him for Mercedes, would the German manufacturer let him move to a rival?
Ocon does look set to stay at Force India but with the team being saved and new owners taking over, will they want a change for next year? One of the investors is Lawrence Stroll (Lance's dad) who will, no doubt, want his son to be driving for the team next season.
