Trulli hopeful of strong Spa weekend

Trulli, who has scored just one point in the last three races, topped the times in a rain-hit morning session and finished in seventh position in the afternoon.

"It was a good Friday for us," said Trulli. "Obviously there is still work to do to get the most out of the car and I need to find a bit more grip at the rear end but all in all I am very happy with the results today.

"I have a good feeling from the car so I hope it will be a competitive weekend for us. The track was wet this morning which meant we couldn't do all of the tests we had planned but we did some laps to better understand the car in those conditions. In the afternoon, when it was dry, the track just got quicker and quicker.

"I was working mainly on race pace today, getting the car set-up in race trim so we have a good balance for Sunday, and it seems to be reacting well."

Team-mate Timo Glock was also encouraged by his first day of work at Spa after finishing as second fastest in the afternoon.

The German, however, said it was too early to judge performances.

"It's hard to draw any conclusions from the wet session this morning but I am pleased to be second in the afternoon; that is very encouraging," Glock said. "The car felt pretty good and the lap times show that.

"Still, there are a couple of areas to improve so we will work on those before qualifying and try to find the perfect aerodynamic balance. I am happy with how things went today and I'm interested to see where we are tomorrow."
