Ferrari boss Maurizio Arrivabene joked that Kimi Raikkonen's complaints at the Singapore Grand Prix highlights the difference between the Finn and race-winner Sebastian Vettel.

Vettel claimed his and Ferrari's third victory of 2015 at Marina Bay with a masterful drive. By contrast, Raikkonen struggled to match the pace of his team-mate but still managed to convert third on the grid to the final spot on the podium.

After the race Raikkonen complained he was struggling with his tyres but Arrivabene said this is more to do with how the 2007 world champion approaches car set-up.

When asked what the problem was on Raikkonen's car, Arrivabene replied: "Kimi is always complaining! No, no problem at all. The usual comments when they are doing the setting of the car, the difference is Seb is quiet and Kimi is screaming, nothing special."

Arrivabene thinks it is natural for one driver to struggle while the other excels depending on the circuit.

"It's like in Monza. In Monza Kimi was very, very strong, here it's Sebastian. Sebastian loves this circuit and is particularly strong here so I don't want to do comparisons between our drivers. They were up to the podium and for me it's enough."

During pre-season, Arrivabene said he would run 100km up the hills of Maranello without shoes if Ferrari won at least four races, a target now within touching distance for the Italian team.

Speaking about that promise, the Italian said: "Actually I said four, this is the reason why we would like to win five!"
