Team boss Franz Tost has excused Sebastien Buemi for a poor performance in Sunday's Hungarian grand prix.
The 20-year-old rookie Swiss finished the Budapest race dead last, behind even his debuting Toro Rosso teammate Jaime Alguersuari.
"I have never been that bad," Buemi told Switzerland's Blick, ruing a race full of mistakes. "I can only say sorry to my team who gave me a good car."
Tost ousted Buemi's 30-year-old teammate Sebastien Bourdais after the recent German grand prix for poor performances, but excuses the rookie.
"Sometimes you have days like that in racing," he said. "Sebastien doesn't need to worry too much, it is a normal part of a 20-year-old's development process."
