Perez hopeful about future: 'Now we understand what is wrong'

Sergio Perez finished sixth at the Dutch Grand Prix on Sunday, recording his best result since the weekend in Miami. As such, the Mexican is moderately positive about the rest of this season, partly due to the fact that, according to Perez, Red Bull finally know where the problems with the car are coming from. But despite this, the six-time Grand Prix winner also stresses that it will not be easy for Red Bull to hold off the McLarens.
