Sergio Perez intends to regain the career momentum he built up prior to his Monaco Grand Prix qualifying crash at this weekend's British Grand Prix.
The Mexican says he feels frustrated that the accident, which forced him to miss the race in Monte Carlo and subsequently the Canadian GP, has interrupted what has been a strong debut season for Sauber, and the 21-year-old intends to get it back on track at Silverstone.
"It [the accident] happened because I was pushing so hard that weekend," said Perez. "I was giving my maximum in Monaco because it is one of those tracks where the driver can make a big difference.
"I was already in Q3, so I was doing a very good job until the crash happened, then I had to lose a weekend. And my teammate, who was starting behind me, finished in fifth position. So it was a very good weekend for him, which could also have been for me, but, unfortunately, I missed the GP and I also missed Canada. In the end, I only have two points, but it has been a very good season so far."
"I think I lost some momentum," he added. "I was going well after Barcelona when I scored points, after Monaco when I was having a very good weekend until qualifying.
"I think now in Silverstone it will be a good moment to restart that momentum again, because we have three races close together so July is an important month for us."
Perez, who finished 11th in the European Grand Prix, also admitted that he was still not 100 percent in Valencia, in spite of finishing ahead of his Sauber teammate Kamui Kobayashi.
"Physically it was a struggle for me, because of the impact on the head I still felt that it was not so easy to come back and jump in the car and drive again," he said. "It took me some time to adapt to everything again but, in the end, everything was fine. I think Valencia was one of the best weekends in terms of giving my maximum, and also all the conditions I faced were very difficult.
"It was not so easy for me to come back and drive, but I did my best and I was still happy to finish 11th and for sure now I will be in a better shape for Silverstone."
