Ocon is currently without a drive for next season after Force India decided to reshape their team after falling into administration and undergoing new ownership.
Toro Rosso, Red Bull’s junior programme, are keen to have promising youngster Ocon on board with their development side.
But the Frenchman is currently under contract with Mercedes so the Silver Arrows would have to let the potential future world champion walk away if a deal is to be struck.
“We have a seat. Mercedes doesn’t have a seat,” Red Bull chief Helmut Marko told Sky Sports.
“If he’s free from all contracts, we could discuss it. I mean all contracts.”
Meanwhile, Toro Rosso announced the re-signing of Daniil Kvyat this morning.
However, the feeder team still have one seat free for next year and they have told current driver Brendon Hartley he will be kept on if he beats team-mate Charles Leclerc, who has will be promoted to the senior Red Bull team at the end of the year, in the final six races.
“Daniil changed,” Marko added.
“He is a far more mature personality. He was working with a different team, so he saw the whole atmosphere and working programme, and he also found out how difficult it is to get a Formula One seat.
“We stayed in contact all over that time. He was well-informed what [Daniel] Ricciardo was going to do.
“He knew it before most other people knew it. He did a smart call just before Ricciardo called me.
“We will give him a third chance because we always believed he’s very fast, but his mental problems, I think he has solved. He is a far more mature driver, and I’m sure we will see some very positive races from him.
“He went to Ferrari [as a test driver] and thought maybe there is a chance or was hoping for a [race] seat.
“When he realised he’s not in the frame, he started talking more intensely with us, and I’m sure we will see the real Kvyat again.”
