Kimi Raikkonen sees no reason why Ferrari cannot catch up with Mercedes this year, but warns "you cannot make miracles overnight".
Ferrari and Sebastian Vettel stunned Mercedes in China to take the victory, but Merc hit back at the Chinese Grand Prix with Lewis Hamilton leading home his team-mate Nico Rosberg.
Vettel and Raikkonen, though, were not completely blown away at Sepang as they managed to keep up with Merc early in the race.
Although they are not quite able to match Merc in every single race just yet, Raikkonen says the team are going in the right direction and is confident they will catch up with the pacesetters.
"Yes. I don't see a reason why [we cannot catch Mercedes this season]," he is quoted as saying by Autosport.
"I think we have good plans already since last year and made big gains and will make big gains during this year.
"Everybody improves and it depends what the rest are doing but we trust the way our team is working altogether and what we are doing.
"So it definitely shows we are going the right way and doing the right things but you need time – you cannot make miracles overnight."
