Nasr's potential Sauber deal held up
Felipe Nasr's hopes of staying at Sauber for the 2017 Formula 1 season are being held up by sponsorship complications, while team-mate Marcus Ericsson is set to stay on board.
Earlier this year Nasr's primary sponsor, Banco do Brasil, changed its president, while a number of other high-powered positions are also understood to be part of a reshuffle.
This is having an adverse effect on negotiations taking place between the bank and Nasr's advisors, and in turn leading to a delay in talks with Sauber.
Autosport understands Sauber is unwilling to wait indefinitely as it wants to have a definitive driver line-up coming out of the final race in Abu Dhabi in just over a fortnight.
Nasr said: "I wouldn't say I'm frustrated. It's just how things are.
"Sauber is still an attractive place to be, it has been getting a lot of people on board, has been restructured, and it's on the way up.
"I only see things changing for the good, with a lot of focus on 2017, and it will be a lot different than this year."
Autosport understands, however, Ericsson and his sponsors - which are understood to have links to Sauber's new owners Longbow Finance - have concluded a deal that will see the 26-year-old Swede remain at the team for a third season.
With no official announcement as yet, when asked about his situation by Autosport, Ericsson said: "There are not so many other options out there, but it's more likely now [staying at Sauber].
"Before anything is done I cannot say anything, but like I've said before Sauber is moving in the right direction, with a lot of good signings, not only for this year but also for next year.
"It's definitely a very attractive option for me.
"A couple of months ago it was not the most attractive option because we struggled a lot in the beginning of the year and it looked quite difficult.
"But we've developed a lot over the second half of the season, and the Sauber team is going to be stronger and stronger moving forwards."
