Kimi Raikkonen has angrily dismissed questions about his motivation and insists that his driving style is behind his current struggles.
Raikkonen could only finish in eighth place in China while team-mate Fernando Alonso notched up Ferrari's first podium finish of 2014.
"It's probably more to do with driving style, plus the weather with the cold conditions and not getting the tyres working," he said of his problems.
"Obviously if there was some issue then we would not be fast or happy with the new tyres, so I think it's a combination of cold conditions, the circuit layout and my driving style.
"I don't think I work the tyres very hard, so when there are cool conditions and wet conditions - for many years it has been hard to get the tyres working. Today it feels that when you have a new tyre it works well until the grip from the new tyres goes away and then you struggle and you have to go slower and the tyres cool down more - everything goes round and round and you cannot fix that.
"It's a thing that everybody hates, but there is not a magic thing and I cannot necessarily change everything with my driving. We just have to work and find some solutions when we have this and hopefully not end up with similar issues. Once you end up with that it's hard to get out of it, especially in the race."
Raikkonen was questioned about his motivation, prompting a curt response.
"I don't know why you always come up with motivation," he said. "If I didn't have motivation I wouldn't be here answering these kinds of questions. It's fuck all to do with that. We have bad races and it's an unfortunate thing, but the aim is to improve and get where we want to be."
