Costa: Ferrari need to win on the streets

Tech director Aldo Costa claims Ferrari need to win on street circuits if want to assert their dominance of the rest of the field.

Ferrari bagged their second successive win on Sunday in Bahrain having previously clinched the Malaysian GP victory as well.

However, while Costa concedes both were circuits that suited Ferrari's F2008, he believes they now have to prove they can win on tracks that have proved problematic in the past.

"The circuits in Malaysia and Bahrain suited the Ferrari perfectly. On other tracks we know we must close the gap and improve, and we are preparing for it," Costa told the Gazzetta dello Sport newspaper.

"Sepang and Sakhir are new-generation circuits, with a certain type of corners and surface. On street circuits, where we already had problems last year, we must demonstrate to have improved.

"Up to now we've raced on peculiar tracks. We'll have to see what happens on the upcoming circuits. The Championship has just started."

As for his predictions for the upcoming Spanish GP, Costa reckons F1 will see another race weekend where Ferrari battle it out with BMW and McLaren.

"It's no different from other circuits," he said. "It isn't so demanding, compared to Malaysia and Bahrain, so I don't expect surprises."
