Kimi Raikkonen led the Ferrari challenge in Baku on Saturday as the Finn beat teammate Sebastian Vettel to take third on the grid.
It was a scrappy session for both Maranello drivers, as for once Ferrari really struggled to get the 2017 Pirellis to work to the optimum.
“I think the biggest issue is the tires,” said Raikkonen. “It’s a bit on edge, they kind of work a little bit… If you get them working well it’s going to make a massive lap time difference, and you can actually push, and now you are a bit on edge all the time because it works or not.
