Of course not, not unless he has a complete change of mental attitude. He is a bottler, plain and simple. Cracks under pressure. Has the talent to win and win easily, but as soon as he needs to do it, mistakes pop in and he flaps.
If he had a weaker team mate he would have won this season, but a driver like Lewis - who lets face it can be a bit of a **** at times - knows how to get into Nico's mind.
