Kimi Raikkonen’s manager David Robertson is convinced that the Finn can only get stronger in 2008 after clinching his first championship.
Robertson believes that having now faced the challenges of adapting to a new team and tyres, as well as joining Ferrari immediately after the end of the Michael Schumacher, Raikkonen will be even harder to beat next season.
"This is a great team," Robertson said. "It is the first time Ferrari have won in three years, so for Michael to go and all these top guys to go and to win again is great.
"Everyone was telling us we had made the wrong decision, but the only one that we were really, really concerned about was Jean Todt. I am a total believer in him, and I know the way he works. He works harder than any of these guys up here.
"So if they have the car next year, Kimi will be unbeatable."
After seeing Raikkonen cause a shock by clinching the title in Brazil, Robertson said he thinks his driver was a more worthy winner than Fernando Alonso or Lewis Hamilton.
"To be honest with you, and not just because I’m his management, but the best man won," Robertson said.
"He would have won but for retirements in the past, and if he would have not had the two failures on the Ferrari this year, it would have been over even before we got here.
"But getting used to the tyres, a new team and all that and still doing it is great. The good news is that you have got a great British driver, who will grow, but he didn’t deserve it this year – in my book anyway."
Robertson said he believed that the Monaco Grand Prix, where Raikkonen crashed in qualifying, marked the turning point of his season.
"He deserved it, he was the man in the last half of the season. I think that his turning point of the season was Monaco. Although that was a mistake, we already saw that he was getting used to those tyres and he felt really confident after that.
"He went to Canada and everything started to come together. The team trained him on these tyres and they are a great team."
