I have been thinking about this a lot, so let me throw these thoughts into the mix and see if anyone thinks the same. As you say, Gasly could end up costing RB second place in the constructors championship. RB's past record is fairly ruthless when it comes to dropping drivers mid season, so who would they replace him with ? None of the current crop of drivers in the RB stable are really up to the job yet. Who, therefore is available until the end of the season. The answer seems obvious to me, Alonso. After the Indy 500 shambles that Maclaren dished up for Alonso, he cut all future commitments with them so is certainly free for a drive for the rest of the season. Pulling in Alonso beside Max would also give added team confidence, because both drivers working as a team are more than capable of putting RB into second place. Alonso said last month that he wouldn't rule out returning to F1, RB would be stupid not to at least talk with Alonso with a view to taking them to the end of this season at least.
