'I don't care' about criticism - Perez

Sergio Perez says he doesn't care if his driving causes criticism but admits he has been "frustrated" by a lack of results at McLaren.

Having joined from Sauber at the end of 2012, Perez could be forgiven for expecting to be in a competitive car this season. However, McLaren has been off the pace and is yet to score a podium in the opening seven races of the year, and Perez said he feels like he's been driving well but not been able to secure the results he had hoped for.

"I feel frustrated; I feel that my performance with McLaren has been good," Perez said. "I have total support from my team, which as a driver is very important; to count on your team's support. And about the criticism, I believe everyone has their own point of view. I'm not here to be liked by everyone, I'm in Formula One to fight for my team - in whatever team I'm in - and if that causes criticism I don't care."

Perez also said that McLaren is still having correlation problems which are hurting its ability to develop the car quickly.

"I believe that the main problem and what has caused these results is the car performance. In terms of vehicle aerodynamics we have way less than expected, we have a problem with the wind tunnel. The wind tunnel is telling us one thing but the reality on the track is much different, so it's very hard to work like that. In this scenario you have to test many things on the track in order to have a good correlation with the wind tunnel."
