Duval led the early levels of the second Assen race from dwelling favorite Robin Frijns after passing polesitter Rene Rast in the beginning, however had slipped to sixth behind teammate Mike Rockenfeller by the point he entered the pits on lap 17 of 31.
Phoenix fitted one other set of moist tyres in anticipation of extra rain regardless of Duval having made a request for slicks, and the French driver made his displeasure clear over workforce radio.
“It’s a big mistake, it’s a big mistake,” he stated in a radio message that was broadcast on the TV feed. “Wet tyres is a big mistake. I told you the track is drying.
“Look all people. F*** man. Forget this app and simply take a look at the climate.”
Phoenix’s decision was vindicated when track conditions worsened in the second part of the race, and even Rockenfeller – who had originally opted for slicks – was forced to stop again to switch back to wet tyres.
Duval, who eventually beat Rast to finish fourth, said slicks would have been the right call if it didn’t rain again, but nevertheless apologised to the team for his choice of words.
“We had been anticipating the observe to dry out rapidly, prefer it’s been drying up [on Saturday] and early on [Sunday],” Duval said after the race.
“We had been fighting the tyres. I might see that the racing line was drying, was not dried but, however we determined to go for [a pit] cease after one thing like 13 or 14 laps [of green flag running].
“Without the rain it would have dried up and the slicks would have been better than the wet tyres. But I couldn’t see the sky and stuff like that.
“I used to be satisfied that it’ll go dry, to a dry observe. That’s why I used to be pissed and I already apologised to the workforce as a result of I shouldn’t react like that.
“At the end, they did make the right call. It was a mistake from my side and that’s it. It did rain again, probably would have been the right call [otherwise]. That’s why we ended up in this situation.”
WRT Audi rookie Fabio Scherer gambled on slick tyres when the observe was nonetheless moist and suffered a large incident on lap 23, which performed a job within the race being red-flagged as marshals recovered his stricken RS5.
It later emerged that the radio channel from race management to Scherer’s automotive was not useful, which implies the FIA F3 graduate was unaware of adjusting observe situations.
After the crash, Scherer branded the principles as “dangerous” which stop groups from talking over the radio except the motive force is within the pitlane or a yellow flag is deployed.
“The problem was I hadn’t had the radio,” Scherer instructed Motorsport.com. “It was a misunderstanding with the tyres and we sadly took the slicks and it started to rain again.
“I used to be asking for a pitstop, nothing in reply. The guidelines ought to permit [drivers] to talk to engineer, however they weren’t so for certain [it’s] harmful. Then I misplaced the automotive in straight line driving so it is actually uncommon.”
“Just for me if you end up on slicks and [the condition] turns to moist, for me [the rules] should be modified as a result of it is anyway harmful.”
