They opened up and took a lot of Italian [Magneti Marelli] engineers from Italy,” Rossi said.”But in the end, at Yamaha, the people are more or less the same. From this point of view, it’s difficult to manage. Especially when we are in these mixed [dry/wet] conditions, we lose a lot from this point of view. ”
