'I must do better' - Vettel admits regrets after poor year
Sebastian Vettel could not hid his disappointment after yet another frustrating day at the Abu Dhabi Grand Prix.
Vettel had taken a risk by starting on the soft tyre at the Yas Marina circuit but was hampered by a technical issue that prevented all cars from using DRS in the early stages of the race.
The team also ended 225 points behind Constructors' Champions Mercedes, and the German driver was understandably frustrated by their failure to compete.
"We didn't have the year we were hoping for, full stop," said Vettel.
"I think the reasons are clear and the lessons are clear. As a team, we must be stronger. As an individual, I must do better - I can do better. It wasn't a great year from my side.

"I don't think it was as bad as it looks because there were many small things leading to not a great picture in the end.
"I'm the first one to look at myself. I'm honest. I know I can do better. That's for sure the target next year - to take that step forward.
"And, hopefully, we get a stronger package as well to fight with Mercedes and Red Bull in the front."
