Two very simple reasons - he needed to get out from under Briatore's shadow, AND he needed the money, it was CRIMINAL his pay with Renualt and absolute joke. The majority of the rest of the paddock were earning more than him in 06, how embarassing - and to Renault it was a disgrace that they wouldn't pay enough to keep him. They truly showed their arrogance here, they thought it was the car, Alonso won in spite of the car! You just need to look at Fisi's results to see thats true! Alonso is as good as he seems and a fitting successor to Schumi!
