Back in Germany, before the Hockenheim GP, Toto Wolff stated: "other teams are interested in Ocon, we should look into that for both our benefit and Esteban's" recognising it wouldn't be fair towards the young driver to keep him away from the track any longer.
Those words may be confirmed by recent rumors that see Valteri Bottas keeping his Mercedes' seat for at least one more year and Ocon heading to Renault.

This scenario wouldn't come complitely unexpected since last summer, prior to Daniel Ricciardo's divorce from the Red Bull team, the 23 year old has already been close to the french team. Moreover, having a compatriot onboard is something that would really please Renault and Ocon changing his Instagram description from 'F1 reserve driver' to 'F1 driver' may just be a little clue to add.
Since Ricciardo already has a contract for next year, Ocon would replace Nico Hulkenberg, who seems likely to join Haas. If everything will be confirmed, the domino would probably kick Romain Grosjean out of the Circus, leaving Gunter Steiner to administrate two drivers that haven't so far got along very well: Nico Hulkenberg and Kevin Magnussen.

Who would for sure cheer in this situation would be Valtteri Bottas: the Finn would hold on to his steering wheel, but for how long? The feeling is that twelve months from now we may find ourselves once again talking about a hot Mercedes' seat, possibly this time threatened by George Russell. No matter in fact how good will Bottas deliver: Toto Wolff is with no doubt looking for a next generation star and is keeping Bottas just as a spare wheel in the meantime. The other top teams already have their future driver between their hands: McLaren's Lando Norris, Ferrari's Charles Leclerc, Red Bull's Max Verstappen are already there. Renault as well has many promising Academy drivers in the Junior Formulas: in Formula 2 alone, Jack Aitken and the two rookies Anthoine Hubert and Guanyu Zhou are well delivering and aiming for the superlicence. Waiting for the eventual officiality of the deal, it may be a good idea to test Ocon while the other youngsters are still learning and then see who's going to be Renault's future bright star.
