So I didn't really see it mentioned much, but is there a reason that massa was almost 1s down on alonso?
The only thing I can think of is that he didn't adapt well enough to the old wing being put back on or they didn't get the setup right when it went back on.
Alonso said the car was un-driveable with the old wing on so maybe Alonso's guys did a better job of compensating for it than Massa's.
