Ferrari technical director James Allison has suggested that Kimi Raikkonen has no excuses for failing to match up to his teammate Fernando Alonso.
The 34-year-old has finished behind Alonso in every race this season, as well as being out-qualified by the Spaniard in four of the six races.
"I'm not sure it's entirely fair to say he is struggling more than Fernando," Sky Sports News quotes Allison as saying.
"The problems Kimi has with the car under braking, downshifting, are the same as Fernando, and pretty much the same as being experienced by other drivers at other teams.
"He's just going a little slower than Fernando at the moment, but that gap is closing as the year progresses."
Raikkonen returned to Ferrari before the 2014 campaign following one year with Lotus.
