Caterham Group's Chief Technical Officer Mike Gascoyne has hinted that the team may opt for a young driver ahead of the 2013 season.
Caterham fielded Heikki Kovalainen and Vitaly Petrov in the 2012 season and finished tenth in the championship.
Gascoyne hinted that neither Kovalainen nor Petrov will return to the team.
"I'm not allowed to [say], but hopefully we will have a young guy in there that will be pushing hard," he told Sky Sports F1.
Petrov's manager, Oksana Kosachenko, believes that Petrov's place at the team is far from secure.
"At the moment, there are a lot of unanswered questions," she told R-Sport. "There are too many things that need to be sorted out. We haven't managed to find new sponsors, and I don't know where the media got that suggestion from."
Gascoyne also believes that Caterham deserved tenth in the championship as they were better than Marussia, and called for a change in the points system to help the team.
"It is what we deserved as the team was in front of Marussia for the whole year - we were a better team than they were. It would have been an anomaly if we hadn't finished tenth because it is just on that one position.
"I think you have to look at putting points all the way down, because when you do it from your best race, we out performed them at every race and we could have lost a huge amount of money on one race and that is not what it should be about".
