Having claimed sixth spot at last weekend's Malaysian GP, Bruno Senna believes that he has begun to show he deserves to be in Formula One.
Senna replaced countryman Rubens Barrichello at Williams this year but his recruitment was met with scepticism with many of the opinion that Williams signed him simply for the money that he brings to the team.
However, the Brazilian put in a strong showing at Sepang, recording a career-highest finish of sixth, despite colliding with team-mate Pastor Maldonado on the opening lap.
"Having a good result takes some of the weight off your shoulders," said the 28-year-old.
"There will always be critics and you are never going to please everybody.
"But for sure, having a strong result will take some wind out of the critics' sails.
"Hopefully I can make sure I keep having strong results to show I deserve my place here," he added.
The eight points Senna collected in Malaysia means that Williams have now already topped the total number (six) that they scored last season.
