Paul Hembery has hit back at Fernando Alonso and Mark Webber after both drivers criticised the Pirelli tyres in Korea.
Qualifying down in sixth place, Ferrari driver Alonso was not happy with the rubber as he felt it had no staying power.
"The tyres cannot do five kilometres. If you push them, you finish the tyres. It's something that is not normal," he said on Saturday. "We have to be honest and the quality of the tyres is very on the limit.
"But I'm not blaming the tyres. That they are not good we all see with our eyes. It's the same tyres for everybody...so it's a compromise we need to find."
Hembery, though, wasn't at all pleased with the Spaniard's comments and hit back, saying he should take a lesson from Sebastian Vettel on how to get the most out of the tyres.
"Of course Alonso is one of the great F1 drivers, so to hear such comments is disappointing and below the standards you would expect from such a Champion," he was quoted by Reuters.
"I can only suggest he goes to ask the soon-to-be four-times Champion how to get the best from the same tyres."
However, the criticism of Pirelli didn't stop there.
In the wake of Sergio Perez's tyre delamination during Sunday's grand prix, Webber stated: "The tyres are wearing a lot and they also explode a bit as well but that's for Pirelli to sort out."
He added: "The drivers aren't super important - it is what other people want."
And again Hembery has hit back saying their complaints are no different to Michael Schumacher's barrage last season.
"They are no different to maybe Michael's last year," the Pirelli motorsport director told Autosport.
"It is maybe a different input if you are having to manage the tyres and you don't want to do it.
"Then you have a different point of view. And there is nothing wrong with a different point of view. It is just not what we've been asked to do at the time.
"If we had been asked to do no degradation and no pitstops then that is what we will have done."
"I can only suggest he goes to ask the soon-to-be four-times Champion how to get the best from the same tyres..."Paul Hembery
