It has previously been rumoured that Esteban Ocon will be replacing Nico Hulkenberg at Renault and reports are now suggesting that Hulkenberg could be taking Romain Grosjean's place at Haas.
FormulaF1 have reported that the announcement of the Ocon to Renault move will be made this weekend and that Haas will announce Hulkenberg as their 2020 driver the following week at the Italian Grand Prix.
If these reports are true then it looks like Grosjean will be out of Formula 1, unless a seat at Williams becomes free if Robert Kubica doesn't stay on.
