Mercedes boss Toto Wolff has slammed Pirelli's decision-making process over the tyre changes lined up for next season.
Pirelli have been very considerate this season, listening to different teams/drivers' preferences to the tyre changes for next season, but it hasn't pleased everyone with the thinner tread that are rumoured for next season.
Wolff is one of the bosses, who clearly disagrees with the changes that are set to take place: "I think there (are) just people who have no clue, that get meddled into the discussion about how the tyres should look like, and how they should behave.
"They should keep out of it, they should listen to the drivers and to the teams, and the teams shouldn't be opportunistic as they have been in the past, thinking that somebody has an advantage or disadvantage and then lobbying for a certain direction."
Wolff didn't single out any of the "clueless" people he was referring to. The Mercedes boss then added: "This is what the story of this thing was, when you remember back six months ago, the discussion about the thinner tread. I mean, it's unbelievable that people said: 'Yeah, Mercedes wants them because they're blistering.'
"Then at the next race, another team was blistering, and they couldn't even finish their stint properly. It's just pathetic how opportunism drives various stakeholders in the business, to push for a direction that is detrimental for the sport."
