Jules Bianchi believes that Marussia must be aggressive in the second half of the Formula 1 season to stay in the top 10 in the constructors' championship.
The Frenchman's ninth place in the Monaco Grand Prix earned the improving team its first points since entering F1 as Virgin in 2010.
If Marussia can keep one of Sauber and Caterham behind it and secure a top 10 place for the second consecutive season, it will be set for a significant financial windfall of around $30 million.
"The best way to defend is to attack and we always have to attack," Bianchi told AUTOSPORT.
"We just have to do everything we can to be in front all of the time, and I'm sure we will be strong until the end of the season.
"Our target is to remain ahead of Caterham and finish 10th in the championship, which will be a massive boost to the team."
Bianchi admitted that he is a little frustrated that Marussia has been less competitive in recent races after showing well earlier in the season.
In Monaco and Canada, the car was close to making Q2 on merit, but it has not been as strong since even though Bianchi capitalised on problems for Pastor Maldonado and Lewis Hamilton and a strategy error by Ferrari to get through Q1 at the Hungarian GP.
"It is a bit frustrating when you have been regularly close to going into Q2 and it is not the case any more," said Bianchi.
"But that's the reality and you have to deal with that and do the best with what you have. This is what we are doing at the moment.
"The result in Monaco was massively important for this season but I knew it did not mean we would be regularly fighting for points.
"We are not able to do that unless we have a strange set of circumstances around us, but we took the opportunity when it came."
