Charles Pic insists he has no regrets over his move from Marussia to Caterham.
Caterham has finished ahead of Marussia in the constructors' championship for the past three consecutive seasons, last year snatching 10th from Marussia in the Brazilian season finale. So far in 2013, however, Caterham has yet to beat Marussia outright in qualifying, even if Pic did split Jules Bianchi and Max Chilton in Malaysia.
The Frenchman says Caterham's form over the opening two grands prix has not given him any misgivings about his switch between camps.
"I don't see things like that," Pic said. "I had a great year with Marussia but now I am very happy to be with Caterham for this year and the future. It's not frustrating at all.
"There are some areas where we need to progress and that's it. It's our job to fix issues and make steps forward."
Pic adds that Caterham will have to wait for upgrades before they can progress as tweaking the setup will not be sufficient.
"We have to wait a few races [for updates] but I have trust in the team so I'm sure we can have a good step forward. With the tire temperature and degradation [it helps] but you cannot find one second with setup.
"Of course we are pushing hard with setup and tire management to optimize these things but at this time we wait for the updates."
