Germany Sunday quotes: Williams

Rubens Barrichello - DNF: We were doing quite well after making a good start and were looking comfortable for a two-stop strategy but then the team came on the radio and called me in with an oil leak. I wanted to continue but the team said there was no way and that was the right decision. It was slippery out there at the start but the main issue was the cold weather making it difficult to get the temperature into the tyres.

Sam Michael, Technical Director: Unfortunately Rubens was out early with an engine oil leak today; we are still investigating the cause. On Pastor's car we called an early first pitstop that moved him right up the order, however we then had too much tyre wear during the second stint, so it may have hurt the race outcome later on. Once we had that tyre wear we decided to risk doing a longer final stint on the prime tyre and that went against us today.
