‘Miracle’ Red Bull haven’t wrapped up title – Domenicali
The comment was a referral to July's German grand prix, when current points leader Fernando Alonso gained an additional 7 points because his teammate Felipe Massa was ordered to give up the win — a practice that is illegal and earned Ferrari a $100,000 fine.
"It would be frustrating because we've obviously worked under the auspices that team orders have been illegal," Horner told BBC radio.
Comments attributed to Ferrari team boss Stefano Domenicali on Wednesday could be seen as a rejoinder to Horner's jibe.
"When you consider the car Red Bull have had this year, in my eyes it's a miracle that we are fighting for this title at all," he is quoted by the German news agency SID.
"If we had that advantage, the championship would be decided already," added the Italian.
Also in the media on Wednesday is McLaren team boss Martin Whitmarsh, amid suggestions Jenson Button should surely now be supporting the charge of his teammate Lewis Hamilton.
Button has declared that, notwithstanding his 42 point deficit to the head of the standings with only two races to spare, he is still aiming for the title.
"I think the right thing is that if he's getting his car in front of all our competitors, then that's the absolute right target and we'll see what happens in the course of the weekend," Whitmarsh said in a teleconference.
But he seemed not to rule out the deployment of a team strategy in Brazil or Abu Dhabi.
"There's a good relationship between the two drivers. I'm sure they're going to cooperate with each other," said Whitmarsh.
"I'm sure he (Button) will do everything he can to fulfill the ambitions of the team," he added.
