Bruno Senna was denied a points finish in the 2012 F1 Belgian Grand Prix as he was forced to make an unscheduled pitstop with just five laps remaining, due to a slow right-rear puncture.

The Brazilian eventually finished down in twelfth place after a clean race on a one-stop strategy had seen him on course for a solid top ten finish at Spa-Francorchamps.

"We went for an aggressive strategy," said the Williams driver. "It looked like the safety car was going to help us, but in the end the pace difference between the cars with newer tyres was too big.

"We then had a slow puncture which meant we needed to pit again before the end. Overall it's a day we want to move on from but we need to learn as many lessons as we can and make sure we're in the best position possible for Monza to score some points for the team."

Following a promising showing in qualifying, Mark Gillan, Williams' chief operations engineer, lamented the team's relative lack of pace on race day.

"Bruno had a very good start from 17th on the grid and pushed hard on a one-stop strategy, but unfortunately we didn't have the pace today to make this work," he confirmed.

Renault Sport's Laurent Debout meanwhile was a bit more upbeat: "Losing some points just at the end with Bruno was a tough pill to swallow, but setting the fastest lap of the race bodes well for Monza," he added.
