Felipe Massa has insisted he is not worried about keeping his place with Ferrari, despite his recent woes.

Massa season so far has been mixed, and while he was third in Spain, the Brazilian has scored just twelve points from the four races since then and most recently spun out early on in Germany.

Ferrari president Luca di Montezemolo came to his defence earlier this month and said he has 'total confidence' in the 32-year-old.

His form - or lack of it - was again brought up though during the Young Driver Test, and Massa again had to fight his corner.

"I know what I have to do [to keep my drive]," Massa told the press today at Silverstone. "I am just concentrating on doing good results. The pace is there so I'm not worried about that. I have shown good pace in most of the races. Things have just happened and I haven't finished a few races. We just need to concentrate and try to keep the pace and just finish. I know if nothing strange happens I will end up in a good position."

"I need to improve my consistency a little bit more to finish the races - that's the most important thing," he added.

Massa completed 69 laps on Friday during the third and final day of the Young Driver Test, and when quizzed about the new Pirelli tyres, he was generally pretty positive in his assessment.

"It is a bit different compared to the tyre we were using two races ago. But I think it is more or less the direction of the last race at the Nurburgring," he continued. "At the last race we had already got the Kevlar construction and so the tyre is a little more consistent now.

"The consistency on the long run is a lot better than in the race here at Silverstone. I think the tyres work in lower temperatures. Nothing happened here with them - there were no punctures and that is the most important thing," he concluded.
