Webber made a bad start on Sunday, losing key places, until he clashed with Pastor Maldonado.
But as he pushed to recover from that spin, his second clash was with Ferrari’s Felipe Massa, before he crashed heavily as Sergio Perez, Romain Grosjean and Paul di Resta fought for position.
“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.
