Aru's last win was a TdF stage becoming top favourite of that race. The situation is exactly the same, he is just further up the trajectory.
Who is further up the trajectory? We have no way of knowing that Pinot's issues will drag on for as long as Aru's have.
It also seemed that, at least towards the end of his stint with UAE, one of Aru's issues was that he was more or less in conflict with the upper management on the team, which I'm pretty sure Pinot isn't. In conflict with the upper management on FDJ, not UAE.
