Oct.5 (GMM) Bruno Senna has dismissed countryman Rubens Barrichello's suggestion he would have scored twice as many points as Williams' 2012 drivers.

F1 veteran Barrichello, who was Pastor Maldonado's teammate last year but is now an Indycar driver, was replaced by Senna for 2012.

The 40-year-old Brazilian has suggested on several occasions this year that he would be doing a better job if Williams had kept him on board.

Senna, who is fighting to keep his seat for 2013 amid rumours Williams is close to replacing him with Valtteri Bottas, said: "Everybody has the right to give an opinion."

Referring to Barrichello, he added: "I think that for him, without being on the track, it's easy to talk.

"I think if you ask everyone from the first to the last team, they would all say they could score more points.

"So it's just an opinion that doesn't matter much," Senna told Brazil's Totalrace.
