Force India have hit back at suggestions that the team have already decided the identity of Sergio Perez's teammate for 2017.
Frenchman Ocon, 20, is a contender thanks to his ties to engine supplier Mercedes, but Force India deputy Bob Fernley says that a decision has not been taken.
"There is a long list of candidates," he told Brazil's Globo.
The reports says that Fernley, team boss Vijay Mallya and other key Force India figures will sit down to discuss the 2017 selection this week.
"We will all give our opinion about who we think is the best package. They should be fast, experienced and help the group to grow.
"We are seeking a consensus solution, which doesn't always happen in the first meeting. Personally, I don't think we will decide the other driver straight away."
Technical boss Green also said that Sauber driver Nasr is in the running, but so too is "everyone who is out of contract".
"We are fourth in the constructors' championship with one of the smallest budgets in F1," he boasted.
Also on the list is the well-backed Jolyon Palmer, whose father Jonathan is among the best connected officials in British motor racing.
"He'd love to continue with Renault, he's put a lot into it this year, he's very bullish and enthusiastic about it," Palmer Sr told The Sun.
"But if that doesn't happen, then of course there's no doubt Force India is a great team. So that's certainly something that we are pursuing."
The others on the list are Kevin Magnussen and the powerfully-sponsored Esteban Gutierrez and Marcus Ericsson, while Mercedes's other junior Pascal Wehrlein is understood to not be rated highly by Force India engineers.
