Pascal Wehrlein emerged as the favourite for the second seat at Sauber for next season, as the number of seats available is reduced to three.
The Mercedes backed driver who has spent a year at Manor, again with the Mercedes engine package, is hotly tipped to be replacing Felipe Nasr for next season. The German was overlooked for the Force India drive, which went to Esteban Ocon after only half a season of Formula One racing behind him compared to his more experienced former teammate. Question marks remain over the financial state of Manor, compounded by the points picked up in Brazil for Sauber which saw them overtake the British for tenth in the constructors championship.
It also emerged today that Banco de Brasil, the key sponsor of Felipe Nasr would be leaving the team at the end of the season, despite the Brazilian stating in the drivers press conference this afternoon that talks are continuing with the Swiss team.
A number of other drivers are clambering for the final remaining places on the grid including Esteban Gutierrez and Rio Haryanto.
