Stefano Domenicali has refused to rule out finding a place at Ferrari for another driver in 2013.
Fernando Alonso is signed up long beyond next season, but his current teammate Felipe Massa will be out of contract at the end of 2012.
At the front of the queue are the two drivers heading up Ferrari’s so-called driver ‘academy’: French GP2 driver Jules Bianchi and 2011 Sauber rookie Sergio Perez.
Asked about Ferrari’s driver plans for Bianchi and Perez in 2013, Domenicali said in Singapore: “For 2013? Ah yes. Bianchi is a great talent and he had a positive season in GP2 but he needs to grow and gain experience next season.
“I cannot say now where he will be,” the Italian told Spanish sports daily Marca, “but for sure we want to invest because we believe in him.
“As for Sergio, he has a contract with Sauber and he also has to grow. It is best not to put any goals at this time. May both of them have a good 2012,” added Domenicali.
Meanwhile, the Italian was asked how much he worries about the rumours Flavio Briatore is waiting in the wings to be the next Ferrari team principal.
Making a circular motion with his fingers, he said: “Zero!”
