Kimi Raikkonen was quick to dispel suggestions that Ferrari could be pole contenders at the Chinese Grand Prix, despite topping the timesheets in FP2.
The Finn's lap of one minute 36.896 seconds on super-soft tyres was the quickest of Friday's practice sessions at the Shanghai International Circuit.
However, the 'Ice Man' was typically cool on his prospects come Saturday and Sunday, highlighting struggles on the harder compounds ahead of a weekend that routinely sees tyres come under heavy duress, as witnessed in FP1 when Felipe Massa and Kevin Magnussen suffered punctures.
Ferrari team-mate Sebastian Vettel was quick to talk up his chances of pushing Mercedes pair Lewis Hamilton and Nico Rosberg in qualifying, but Raikkonen suggested raceday could be a struggle.
"It's been quite a tricky day," Raikkonen said. "I don't know if it's the conditions or the wind or something but I was sliding a lot and obviously not feeling very nice.
"Once we put the super-soft tyres on we have more grip from the tyres and that helps.
"For whatever reason we've been quite struggling apart from the super-soft tyre.
"Our car is nice but it's just the other tyres are very difficult to get any grip from.
"But I had a pretty OK lap and the long run on the super-soft was OK.
"I only used the medium in the morning and it didn't feel very good but also the soft didn't feel great and then the super-soft was the best so far.
"The wind conditions are making it very tricky and hard to read."
