Newly-crowned British F3 champion Felipe Nasr is being targeted by two of F1's three biggest teams, boosting his hopes of graduating to the top flight in the next couple of years.

Managed by former F3 pilot Steve Robertson, who also oversaw Kimi Raikkonen's rapid rise to F1, Nasr's rampage through both the Sud-Am and British championships in 2010-11 has awakened interest from both McLaren and Ferrari, according to Brazil's Globo Esporte.

"I can not say anything," the 19-year old admitted, "I have mentioned these two teams because of Steve's very good relationship with them but I know that, in time, he can negotiate an opportunity to test. I think, at the time Steve sees that I am ready, he will contact those teams."

Having reportedly turned down interest from Red Bull, which wanted the Brazilian to join the development scheme that has delivered the likes of Sebastien Buemi, Jaime Alguersuari and, most recently, Daniel Ricciardo to F1 - but also spat out the likes of Brendon Hartley, Adrian Zaugg and Robert Wickens - Nasr admits that Robertson's record of getting drivers to the top flight - the Briton was also involved with Jenson Button's early career - was of greater importance to him.

However, the Brazilian's path to the top could be left to rely on his own results and Robertson's negotiating skill as he lacks the sponsors to take him straight to the grand prix grid. Indeed, such is his dearth of backing, Nasr may find himself in the World Series by Renault, rather than GP2, next season, and will hope to make the same sort of impression as Sebastian Vettel and Robert Kubica, both of whom made it to F1 without GP2.

Nasr, who clinched the British F3 title with Carlin at Rockingham last weekend, still has two more rounds of the series to go, but will look to Robertson to secure him an outing in F1's end of season 'young driver' test in Abu Dhabi.
