Kimi Raikkonen: Ferrari's current Formula 1 form is painful

His team-mate Sebastian Vettel finished 32 seconds adrift of winner Lewis Hamilton in fifth and 15s behind fourth-placed Nico Rosberg. Raikkonen was five seconds off Vettel in sixth.

With Daniel Ricciardo and Max Verstappen scoring Red Bull's first double podium since last year's Hungarian Grand Prix, the team moved ahead of Ferrari into second in the constructors' championship.

In the last three grands prix, Ferrari has failed to score a single podium and taken just 50 points to Red Bull's 80, having been a contender for a race win in the season-opening race in Australia.

"Everybody can see where we finished and it's obviously a bit painful for all of us," said Raikkonen.

"But this is how it is right now and we just have to work hard and improve.

"Obviously we want to win and beat everybody, that's always the aim in racing.

"We were ahead of Red Bull, now Red Bull has got ahead of us.

"Hopefully we can challenge both of them [Red Bull and Mercedes] later on but it's not going to be easy."

There is now a four-week gap between grands prix, with Belgium hosting the next race on August 28.

Raikkonen said Ferrari would have to work hard before then to find some answers if it wants to fight at the front.

"Hopefully we find some tools to make our car quicker," he said.

"Obviously, Spa is a completely different layout to here so it might be different.

"But we have work to be done to get where we want to be. We need to improve."

Raikkonen, who is fourth in the drivers' standings, admitted Ferrari's race pace was not quite what it was expecting come Sunday.

"That was what we were hoping [to have good race pace], but it didn't happen and we just weren't fast enough so it's as simple as that unfortunately," he said.

"It wasn't too bad when we had fresh tyres, but they seemed to drop off quite quickly."
