Sebastian Vettel says there are several issues he still needs to resolve with respect to his move from Ferrari to Aston Martin.
The four-time F1 world champion had a torrid time at the Bahrain Grand Prix, finishing the race in 15th place. To make matters worse the German ended the weekend with five penalty points tacked onto his license after incidents in qualifying and the race.
As a result Vettel confirmed he is still sorting several things out on the AMR21 after missing a bulk of the preseason test.
"There's a lot of things that are fighting me, so that I can't really focus on driving," Vettel said in a post race press conference. "We need to address them and try and fix them but I'm not at home in the car.
"I obviously adapt to how the car wants to be driven but there's a lot of things that add certian inconsistency that don't help so these things we need to get on top of.
"Obviously, I'm a bit sorry for such a bad weekend because I know how much prep goes in before the start of the season and then the first race etc. But on the other hand, it can only go up from here.
"As I said we we learned a lot of things. So it's a lot of work ahead of us but it's what it is and we have to tackle it step by step."
Vettel also offered an explanation as to his incident with Esteban Ocon, where the German driver punted the Frenchman into a spin causing both cars to lose valuable time.
"I thought he would stay right and then when he came back left just ahead of me, I locked so it's probably my fault," Vettel said.
Despite the difficult start to the season, Vettel remains optimistic about what he can accomplish with Aston Martin over the course of the season.
"I think the next couple of races will be very good for us," Vettel said.
"Yeah, we've tried a lot with a car to the setup and as I said there's a lot of things that still don't work the way they should. Once we fix them and we get on top of the setup to know where the car wants to be fast then I think it can only get better."
