Sauber driver Sergio Perez was left disappointed after retiring from the Indian Grand Prix.
Perez picked up a puncture when attempting to pass Daniel Ricciardo, ending his race.
"Today was a total disappointment. First of all I had to pit after 14 laps because the front left tyre was blistering badly. We don’t know yet why this happened.", he said.
"I wanted to recover the lost positions but touched Daniel Ricciardo’s front wing when I overtook him. The rear right tyre came off the rim and damaged something at the rear of the car. So my race was over after 20 laps".
Kamui Kobayashi struggled to fourteenth place and admits that his incident with Pastor Maldonado was strange.
"I always had someone in front of me but not enough straight line pace to overtake. This was frustrating", he said.
"I was stuck behind Daniel Ricciardo and there was nothing I could do. The issue with Pastor Maldonado was a bit strange. He had overtaken me but then he suddenly came on my racing line again. I could not avoid having contact".
