Kimi Raikkonen says the disrupted practice sessions for the Russian Grand Prix meant Ferrari "learned absolutely nothing".
The opening session was delayed by half an hour due to a diesel spillage on the circuit, with the first 30 minutes spent cleaning the track before an hour of running took place on a very slippery track. FP2 was then hit by heavy rain and Raikkonen - who didn't run at all in the afternoon - says there was nothing to be gained.
"In the end we had to do some running [in FP1] to see if there were any issues with the car, but one part of the track was almost dry and the other side was fully wet, so we learned absolutely nothing," Raikkonen said.
"It was the same for everybody, but unfortunately [the diesel spillage] happened in the only dry session we had today, because the second one was washed away."
And Raikkonen says Ferrari will find out on Saturday if it can cut the gap to Mercedes with running on the soft and supersoft tyre.
"We’ll see tomorrow. Hopefully it will be dry and we’ll see how the tyres work. Today was not very nice and we didn’t learn much, so if it’s dry we can do some more tests."
