Davidson would do nicely, he'd help with car development, extremely underrated, Sir Frank has tried to sign him before (when Honda's fat cats got in the way) and it would be nice to have a British driver at the wheel of a Williams car once again.
This is a big worry for me now;
The German is worried after Bahrain: ''I didn't have a good feeling with the car. In the race it was a bit better than in qualifying, but that was only because I found my rhythm. The other teams will make a big step forward in Barcelona. We've already introduced half of our development package here in Bahrain but we didn't make any progress. I hope that we won't fall back in Barcelona.''
I'm not sure if that's Nico having yet another sulk, but I suppose one comforting matter could be that the updates won't work until the other "half" of the upgrades have been attached to the car. I am intrigued to see what these updates are...
