Caterham replaced their lineup with the likes of heavily sponsored Charles Pic and Giedo van der Garde thanks to the ever-increasing influence of the 'pay driver'.The Finnish news media tried without success to get comment from Kovalainen when news of the Netherlands' Van der Garde broke. THERE'S STILL HOPEThis was interpreted as a clear sign by some that the 31-year-old’s F1 career is over. The former McLaren and Renault driver has been paid by Caterham for the past three seasons, but Salo insisted: "I don't think so."I think he can still come back," the 46-year-old former Ferrari and Sauber driver turned TV commentator told the broadcaster MTV3. "It often happens that there are new, young drivers but their song can be short if they make a lot of mistakes. That's when people start looking around again for an experienced professional."Heikki had long negotiations with Caterham,but in the end they chose money over skill."
