And although he has yet to beat his best 11th place finish from Monaco, Caterham's new team principal Manfredi Ravetto thinks Ericsson's performance in Singapore - where he finished ahead of main rivals Marussia in 15th - was a breakthrough.
That form has left Ravetto convinced that it should keep Ericsson for 2015.
"I saw a strong Ericsson in Singapore who did the best race of his season," Ravetto told AUTOSPORT.
"I am sorry for the opportunities he missed in free practice and qualifying due to technical issues, because without them I am sure he would have started in a better position.
"Even so, the fact is he superbly managed to keep both Marussias behind him and did a really fantastic race on a very difficult track.
"We are really very happy with the progress he made and our doors are open for him for next year.
"We have started talking to his management and to his financial backers because this year the team invested in his rookie development.
"Next year we would be delighted in having him again in our car and taking the fruits of this investment, rather than seeing him deliver for somebody else."
