I agree with the first part, but I am very unsure about the second (that the reason was small money differences).
Hopefully some Spanish guys can enlighten is.
In other news I'd guess Sordo is quite set for Greece. But might this threaten his place for Catalunya? (I guess Breen needs 5th or better and beating one of the 3 Toyotas/2 Hyundais on Ypres).
