Red Bull's Dr Helmut Marko has pointed some criticism at Mark Webber, after the Australian bowed out of mathematical contention for the 2012 title with a messy race in Abu Dhabi.
Webber made a bad start on Sunday, losing key places, until he clashed with Pastor Maldonado.
"You can't have more errors than that in one race," Red Bull's driver manager Marko is quoted by Bild newspaper.
"That was not a good day for him.
"The start was no good, and the accidents were not good.
"It's too bad, because it affects us in the constructors' championship."
Indeed, Red Bull could have wrapped up the teams' title in Abu Dhabi simply by scoring more points than Ferrari or McLaren.
