He's made himself the target with his lacklustre start to the season. Given Helmut's history of not entertaining underperformance, Gasly's on borrowed time. Literally the only thing saving his career right now is the fact that RB have no good drivers available to replace him. Their only real choice is Kvyat, but putting him back in the big team will involve eating a lot of humble pie. Also, if they do decide to promote Kvyat again, what happens if he also gets shown up by Verstappen and is off-pace? Do they demote him again? Imagine the fallout from that one.
