Marko, himself a former F1 driver and head of Red Bull's driver development program since 1999, said of Gasly's removal from the team, as per GPFans: "Gasly has problems in traffic, he loses places and he can't overtake".
Gasly has been replaced by the man who originally took his place at Toro Rosso, Thai-British Alexander Albon, who this season has himself earned 16 points in a vastly inferior auto that of the man he has replaced at Red Bull.
However, after 12 races, in which he only once beat his team-mate Max Verstappen, Red Bull's patience wore out.
However, it continues what has been a rollercoaster year for Albon, who thought he'd be racing with Nissan in Formula E before joining Toro Rosso and now finds himself set to take on the best in the business from Spa-Francorchamps next month.
Gasly has struggled as the No 2 driver in his debut season with Red Bull, finishing higher than sixth on only two occasions.
Before the Daniil Kvyat saga, there was Christian Klien, who was dropped just three races from the end of 2006 in his second season with Red Bull.
"The point is that we perform better with the other vehicle and thereby gain more points for the team".
"That's why we originally wanted to compensate for the missing horsepower with a chassis that is very aerodynamically efficient".
"But we corrected that and at the last races we were nearly on par with Mercedes, while we have definitely overtaken Ferrari".
"I think we will be competitive on every kind of racetrack in the second half of the season".
