I bet you're a (Brasilian) fanboy of Felipe Nasr, and there's nothing wrong with that, but your mission here is simply mud slinging in hopes that Helmut Marko might hear you.
The problem is, you should make a case for your guy instead.
Da Costa has beaten Nasr in Macau last year, for instance. Nasr is not bad at all, rich kid and all, but I very very seriously doubt he's any better than da Costa.
Two years in GP2 and how many wins, poles and fastest laps does he have? Less than half the points of his teammate in his first year. 9 podiums in 42 starts.
Yes I'm brazillian, and not a fan (at least, not yet) of Felipe Nasr.. By the way, this topic is not to discuss Nasr, but to discuss the previous achievements of da Costa, there aren't many by the way..
Another thing, Nasr is not a "rich boy".. He earned all the financial support he has now after winning F-BMW on his rookie year with more than 100 points over the second place, and the British F3 with 81 points over the second place, who was, by the way, Kevin Magnussen..
About GP2 victories, if you research a little bit, you will see that DAMS didnt really care about their second car last year, and that Carlin NEVER fought for the title in GP2, still, he is the most regular front runner in the series and is still fighting for the championship..
Now tell me.. Appart from Macau (one race) and F-renault NEC, what else did da Costa do in terms of titles?? bet you wont spend a lot of time righting it down for me..
And no, Im not trying to put da Costa down because of the Toro Rosso seat. I also know Nasr doesnt have a chance there cause he is not a Red Bull driver.. In my oppinion, Marko should choose Kvyat or even Sainz Jr, cause da Costa still needs some time to be ready for F1
