Looks like Williams has choosen to change the driver.
We have a list of 4 drivers according to ESPN who can take hims spot
Liam Lawson, Mich Schumacher, Franco Colapinto and Felipe Drugovich.
It is not clear if the change will be done before or after next race, GP of Monza,
Williams' decision to replace Sargeant as soon as possible was the best decision for them, because instead of improving his performance, Sargeant actually caused more damage to the car he was driving and that burdened the team with the cost of the damage they needed to pay. I feel that Mick Schumacher might be a potential replacement that Williams could take. Although at the beginning of his career in F1 before he did not have a good performance, but MSC seems to have fixed some things and is more mature to be given the opportunity to drive with Williams.
