Rosberg believes that Ferrari have "way too little drag"

Former Formula 1 World Champion Nico Rosberg believes that Ferrari have not got the right aero set up for their car. Currently Ferrari are very fast in a straight line but they lose a lot of speed in the corners, where Mercedes are quicker. 

"They have way too little drag and just way not enough downforce in the corners," Rosberg said to Motorsport.com. "That's where they're losing a lot of time. It's not ideal for the fastest possible lap. So they're just in the wrong place with their car."

"They were trying this weekend to put on some more rear wing but they didn't have the bigger rear wing they needed," said Rosberg.

"They need to produce that but also just putting on rear wing is not an efficient way because it's just a 1:1 'increase downforce, increase drag'.

"That's not the way to go. The way to go is to take it from other places in the car, like front wings, endplates. That's what that really need to focus on now. But that's a lot of work. It's going to take time, it's not great."

Some think that with the long straights at Baku that Ferrari might be fast there but the circuit also has long slow corners where they will lose time. It will be interesting to see if Ferrari change their set up or try and improve the one they are using now.
