Kimi Raikkonen bemoans 'useless' Friday in Sochi

Kimi Raikkonen said it is impossible to judge the pecking order for the Russian Grand Prix, branding the farcical opening day of practice "useless".

Raikkonen completed 16 laps in an opening morning delayed by a bizarre diesel spill by a track vehicle before the session started, before staying in the garage throughout the washed out FP2. Mercedes is wary of a Ferrari resurgence similar to its dominant form at the Singapore Grand Prix due to Pirelli's decision to bring soft and super-soft tyres to Russia.

However, Raikkonen says Ferrari is nowhere closer to knowing where it stands this weekend.

When asked if he can fight Mercedes for a spot on the front row, Raikkonen said: "It's too early to say. Obviously we didn't learn anything today so we will have to see tomorrow. I think we should be okay, we'll see how far we get but we'll try."

Raikkonen expects a busy FP3 as team's play catch-up on Saturday morning ahead of qualifying.

"Unfortunately the only the dry session today it was wiped away because of that - they had to wash the circuit so it was a bit useless. But what can we do, it's one of those things.

"Obviously it's not ideal but it's the same for everyone, we'd rather do it in practice than in good conditions. Today was an odd day, nothing was learned, so we will try to make the best out of tomorrow and do the normal things tomorrow."
