Toto Wolff has apologised to Lewis Hamilton for the "undriveable" car Mercedes provided the seven-time World Champion with for the Emilia Romagna Grand Prix.
Hamilton finished outside the points at Imola after spending much of the race trying and failing the pass the AlphaTauri of Pierre Gasly.
The 37-year-old's misery was compounded by the fine performance of his teammate, George Russell, who was able to fend off Valtteri Bottas during the final laps to place fifth.
Speaking directly to Hamilton via the team radio after the race, Wolff said: "Sorry for what you have needed to drive today. I know this is undriveable and not what we deserve to score as a result.
"We'll move from there, but this was a terrible race. We will come out of this."

Wolff: We need to fix the car
Wolff has once against stressed the need for Mercedes to fix their struggling car, with porpoising proving to be their big problem for the fourth race running.
The team's public apology to their driver comes at the end of a dismal weekend for Hamilton that saw him fail to score a single point.
"I had a little bit of an exchange [with Hamilton] and said sorry for the car that he needs to drive at the moment and that we will sort it out. He acknowledged, so it's okay," Wolff told Sky Sports F1.
"I mean, [the race was] really bad. He got squeezed by the Alpine, and the other two cars under-cut [him], and there is just no overtaking when you're in a DRS train.
"I think we saw with George how the car can drive if you're in free air, but we're not worthy to be a World Champion. We just need to fix the car."
