He blamed both drivers first and foremost.You skipped all the polemics when they crashed and blamed Webber (unfairly), but that's fine.
Webber also said on TV his strategy on Abu Dhabi was a trap for Ferrari, but whatever.
Most blamed the young German Vettel for the manoeuvre. But while Horner attempted to divide the blame between his two drivers, he implied that the Australian Webber was the more culpable. "They should have given each other more room," he said. Then he added: "Sebastian had a pace advantage on that tyre. Mark kept his line and squeezed him."
Regarding Abu Dhabi, again, vettel took pole, had webber just qualified better or gee i dont know, done a better job through the season while Vettel had problems of his own he would have been a champion!
Same as this year, Vettel struggles, Webber shines, then just chokes as everyone else is getting their act together.
