Wolff lashes out at Las Vegas critics: You're talking about a f***king drain cover!

Mercedes Team Principal Toto Wolff has lashed over "completely ridiculous" criticism of the Las Vegas Grand Prix.

Track time was cut short after nine minutes of action, when Carlos Sainz stopped out on track after hitting a drain cover.

The FIA red flagged the session and subsequently canceled it, with it later emerging that a "single water valve" had come loose.

The remainder of the days sessions have been delayed while work is ongoing, however Wolff believes this should not cast doubt over the rest of the weekend.

“That is not a black eye [for F1]. This is nothing," Wolff told media, including RacingNews365.

"We have a free practice we are not doing, and no one is going to talk about it tomorrow.

"It is completely ridiculous that you are speaking about a f****g drain cover that’s been undone."

Wolff: Give credit to the people that have setup this race

Wolff continued by expressing his support for Liberty Media, and believes that the success of the race should be judged by the end of the day on Saturday.

"It has happened before, it's nothing, it's FP1. Give credit to the people that have set up this Grand Prix, that have made this sport much bigger than it ever was," he continued.

"Liberty has done an awesome job and just because in FP1 a drain cover has become undone, we shouldn't be we shouldn't be moaning.

"The car is broken, that's really a shame for Carlos and it could have been dangerous. So between the FIA and the track, everybody needs to analyse how we can make sure this is not happening again.

"But talking here about a black eye for the sport on a Thursday evening, nobody watches FP1 in European time anyway."
