Cape Town - With Ferrari and Mercedes locked in an intense tussle for this year's titles, Kimi Raikkonen reckons it is the "small things" that will make the difference.
As Formula 1 headed into the summer break, Raikkonen's team-mate Sebastian Vettel increased his lead in the Drivers' standings to 14 points over Lewis Hamilton with a win at the Hungarian Grand Prix.
Leading home a Ferrari 1-2, the Scuderia also took a chunk out of Mercedes lead in the Constructors' Championship, narrowing the deficit to 39 points.
It is shaping up to be a thrilling run-in to the conclusion of the season with Raikkonen believing it is the little things that will count.
"It depends on which tyres we have, what weather conditions we're going to face, lots of things, small things that make a difference," he said.
"Now we take the holiday and see what happens in Spa, but if you look at it now, it's not going to be as easy for us there as it was in Hungary. We obviously try to improve and hope to be quick there too."
He added: "For sure there are some circuits that suit us better.
"There are areas where we have to improve, especially in qualifying, where Mercedes has better horsepower, but it depends on many things.
"You cannot purely look at the layout of the circuit and say "this is going to be good for us" or "this is going to be good for them."
